DETAILED DESCRIPTION
[0087] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.
[0088] The imaging lens according to the present embodiment consists of, in order from the object side to the image side, a front group Gf, an aperture stop St, and a rear group Gr which has a refractive power. Further, in the imaging lens according to the present embodiment, the front group Gf and the rear group Gr are combined, and include at least five negative lenses and at least three positive lenses. In such a case, the configuration is advantageous for suppressing various aberrations.
[0089] For example, the lens groups of the imaging lenses of
[0090] A lens closest to the object side in the front group Gf is a first lens as a negative meniscus lens which has a convex surface facing toward the object side. A lens, which is second from the object side in the front group Gf, is a second lens as a negative lens which has a concave surface facing toward the image side. In such a case, the configuration is advantageous for achieving an increase in angle of view. More specifically, it is preferable that the second lens is a negative meniscus lens which has a convex surface facing toward the object side. In such a case, the configuration is more advantageous for achieving a further increase in angle of view. For example, in the imaging lenses of
[0091] The front group Gf includes at least three negative lenses, which include the first lens and the second lens, and at least one positive lens. In such a case, the configuration is advantageous for suppressing various aberrations while ensuring a wide angle of view.
[0092] It is preferable that the front group Gf includes a cemented lens. In such a case, the configuration is advantageous for suppressing chromatic aberration.
[0093] It is preferable that a lens closest to the image side in the front group Gf is a lens which has a concave surface facing toward the object side. In such a case, the configuration is advantageous for suppressing astigmatism.
[0094] It is preferable that a lens closest to the image side in the rear group Gr is a lens which has a convex surface facing toward the image side. In such a case, the back focal length is prevented from becoming excessively long. Therefore, the configuration is advantageous for achieving reduction in total length of the optical system.
[0095] In the rear group Gr, it is preferable that the number of cemented surfaces to which lenses adjacent to each other are cemented is equal to or less than 2. In such a case, the configuration is advantageous for suppressing various aberrations other than the chromatic aberration.
[0096] It is preferable that the front group Gf or the rear group Gr includes at least one lens which moves along the optical axis Z during focusing. Focusing is performed by movement of at least one lens included in the front group Gf or the rear group Gr. By providing such a focusing function, it is possible to provide a high additional value as the imaging lens. Examples 1 to 9 and 19 to 22 to be described later correspond to the configuration. For example, in the imaging lenses of
[0097] Hereinafter, preferable configurations of the imaging lens of the present disclosure relating to conditional expressions will be described. In the following description of conditional expressions, in order to avoid redundancy, the same symbol is used for the same definition, and the duplicate description of the symbol is omitted. In the following description, the imaging lens according to the embodiment of the present disclosure is also simply referred to as an imaging lens in order to avoid redundancy.
[0098] Assuming that a maximum half angle of view in a state where the infinite distance object is in focus is ?m and the unit of ?m is degrees, it is preferable that the imaging lens satisfies Conditional Expression (1). By not allowing the corresponding value of Conditional Expression (1) to be equal to or less than the lower limit thereof, a wide angle of view can be ensured. Therefore, high additional value can be achieved as the imaging lens. By not allowing the corresponding value of Conditional Expression (1) to be equal to or greater than the upper limit thereof, it is easy to achieve a balance between optical performance and reduction in size.
65<?m<130(1)
[0099] In order to obtain more favorable characteristics, it is preferable to use any of 75, 80, or 85, instead of 65 which is the lower limit of Conditional Expression (1). Further, it is preferable to use any of 125, 120, or 115, instead of 130 which is the upper limit of Conditional Expression (1).
[0100] Assuming that a back focal length of the whole system at an air-equivalent distance in a state where the infinite distance object is in focus is Bf and a focal length of the whole system in a state where the infinite distance object is in focus is f, it is preferable that the imaging lens satisfies Conditional Expression (2). By not allowing the corresponding value of Conditional Expression (2) to be equal to or less than the lower limit thereof, it is possible to suppress an increase in diameter of the lens closest to the image side in the rear group Gr. By not allowing the corresponding value of Conditional Expression (2) to be equal to or greater than the upper limit thereof, the back focal length is prevented from becoming excessively long. As a result, the configuration is advantageous for achieving reduction in total length of the optical system.
0.25<Bf/(2?f?sin(?m/2))<2(2)
[0101] In order to obtain more favorable characteristics, it is preferable to use any of 0.27, 0.29, 0.31, 0.33, 0.35, or 0.37, instead of 0.25 which is the lower limit of Conditional Expression (2). Further, it is preferable to use any of 1.8, 1.6, 1.4, 1.2, 1, or 0.95, instead of 2 which is the upper limit of Conditional Expression (2).
[0102] Assuming that a sum of the back focal length in terms of the air-equivalent distance and a distance on the optical axis from a lens surface closest to the object side to a lens surface closest to the image side in a state where the infinite distance object is in focus is TL, it is preferable that the imaging lens satisfies Conditional Expression (3). By not allowing the corresponding value of Conditional Expression (3) to be equal to or less than the lower limit thereof, the configuration is advantageous for suppressing various aberrations. By not allowing the corresponding value of Conditional Expression (3) to be equal to or greater than the upper limit thereof, the configuration is advantageous for achieving reduction in total length of the optical system.

Further, it is preferable to use any of 7.5, 6.7, 6.4, or 6.3, instead of 8.5 which is the upper limit of Conditional Expression (3). For example, it is more preferable that the imaging lens satisfies Conditional Expression (3-1).
4.4<TL/f<6.7(3-1)
[0104] It is preferable that the imaging lens satisfies Conditional Expression (4). By not allowing the corresponding value of Conditional Expression (4) to be equal to or less than the lower limit thereof, it is possible to suppress an increase in diameter of the lens on the image side of the rear group Gr. By not allowing the corresponding value of Conditional Expression (4) to be equal to or greater than the upper limit thereof, the back focal length is prevented from becoming excessively long. As a result, the configuration is advantageous for achieving reduction in total length of the optical system.
0.05<Bf/TL<0.35(4)
[0105] In order to obtain more favorable characteristics, it is preferable to use any of 0.07, 0.09, or 0.11, instead of 0.05 which is the lower limit of Conditional Expression (4). Further, it is preferable to use any of 0.33, 0.3, or 0.28, instead of 0.35 which is the upper limit of Conditional Expression (4).
[0106] Assuming that a focal length of the front group Gf in a state where the infinite distance object is in focus is ff, it is preferable that the imaging lens satisfies Conditional Expression (5). By not allowing the corresponding value of Conditional Expression (5) to be equal to or less than the lower limit thereof, the negative refractive power of the front group Gf is prevented from becoming excessively strong. As a result, the configuration is advantageous for achieving reduction in total length of the optical system, and it is easy to ensure the amount of peripheral light. By not allowing the corresponding value of Conditional Expression (5) to be equal to or greater than the upper limit thereof, the positive refractive power of the front group Gf is prevented from becoming excessively strong. As a result, it is easy to correct spherical aberration and field curvature.
?0.4<f/ff<0.4(5)
[0107] In order to obtain more favorable characteristics, it is preferable to use any of ?0.3, ?0.2, or ?0.1, instead of ?0.4 which is the lower limit of Conditional Expression (5). Further, it is preferable to use any of 0.3, 0.2, or 0.1, instead of 0.4 which is the upper limit of Conditional Expression (5).
[0108] Assuming that a focal length of the rear group Gr in a state where the infinite distance object is in focus is fr, it is preferable that the imaging lens satisfies Conditional Expression (6). By not allowing the corresponding value of Conditional Expression (6) to be equal to or less than the lower limit thereof, the positive refractive power of the rear group Gr is prevented from becoming excessively weak. As a result, the configuration is advantageous for achieving reduction in total length of the optical system, and it is easy to correct spherical aberration. By not allowing the corresponding value of Conditional Expression (6) to be equal to or greater than the upper limit thereof, the positive refractive power of the rear group Gr is prevented from becoming excessively strong. As a result, it is possible to prevent spherical aberration from being excessively corrected.
0.1<f/fr<1.3(6)
[0109] In order to obtain more favorable characteristics, it is preferable to use any of 0.2, 0.3, or 0.4, instead of 0.1 which is the lower limit of Conditional Expression (6). Further, it is preferable to use any of 1.1, 0.9, or 0.7, instead of 1.3 which is the upper limit of Conditional Expression (6).
[0110] Assuming that a distance on the optical axis Z from the lens surface closest to the object side to the aperture stop St in a state where the infinite distance object is in focus is Ts, it is preferable that the imaging lens satisfies Conditional Expression (7). By not allowing the corresponding value of Conditional Expression (7) to be equal to or less than the lower limit thereof, an object side space more sufficient than the aperture stop St can be ensured. Therefore, an appropriate number of lenses are disposed. Thereby, the imaging lens can be configured without forcibly reducing an absolute value of the curvature radius of the lens. Thereby, it is easy to suitably correct various aberrations. By not allowing the corresponding value of Conditional Expression (7) to be equal to or greater than the upper limit thereof, the position of the aperture stop St can be prevented from becoming excessively close to the image plane Sim. As a result, it is possible to prevent the incidence angle of the off-axis principal ray, which is incident to the imaging element disposed on the image plane Sim in the imaging apparatus, from becoming excessively large.
0.1<Ts/TL<0.9(7)
[0111] In order to obtain more favorable characteristics, it is preferable to use any of 0.2, 0.25, or 0.3, instead of 0.1 which is the lower limit of Conditional Expression (7). Further, it is preferable to use any of 0.8, 0.7, or 0.6, instead of 0.9 which is the upper limit of Conditional Expression (7).
[0112] Assuming that a focal length of the first lens is fL1, it is preferable that the imaging lens satisfies Conditional Expression (8). By not allowing the corresponding value of Conditional Expression (8) to be equal to or less than the lower limit thereof, the negative refractive power of the first lens is prevented from becoming excessively strong. As a result, it is easy to achieve an increase in angle of view. By not allowing the corresponding value of Conditional Expression (8) to be equal to or greater than the upper limit thereof, the negative refractive power of the first lens is prevented from becoming excessively weak. As a result, it is easy to satisfactorily correct astigmatism.
?0.6<f/fL1<?0.1(8)
[0113] In order to obtain more favorable characteristics, it is preferable to use any of ?0.5, ?0.45, or ?0.4, instead of ?0.6 which is the lower limit of Conditional Expression (8).

[0114] Assuming that a focal length of the second lens is fL2, it is preferable that the imaging lens satisfies Conditional Expression (9). By not allowing the corresponding value of Conditional Expression (9) to be equal to or less than the lower limit thereof, the negative refractive power of the second lens is prevented from becoming excessively strong. As a result, it is easy to achieve an increase in angle of view. By not allowing the corresponding value of Conditional Expression (9) to be equal to or greater than the upper limit thereof, the negative refractive power of the second lens is prevented from becoming excessively weak. As a result, it is easy to satisfactorily correct astigmatism.
?1<f/fL2<?0.1(9)
[0115] In order to obtain more favorable characteristics, it is preferable to use any of ?0.95, ?0.9, and ?0.85, instead of ?1 which is the lower limit of Conditional Expression (9). Further, it is preferable to use any of ?0.2, ?0.25, or ?0.3, instead of ?0.1 which is the upper limit of Conditional Expression (9).
[0116] Assuming that a paraxial curvature radius of an object side surface of the first lens is RL1f and a paraxial curvature radius of an image side surface of the first lens is RL1r, it is preferable that the imaging lens satisfies Conditional Expression (10).

By not allowing the corresponding value of Conditional Expression (10) to be equal to or greater than the upper limit thereof, it is easy to satisfactorily correct spherical aberration. Further, by not allowing the corresponding value of Conditional Expression (10) to be equal to or greater than the upper limit thereof, the refractive power of the first lens is prevented from becoming excessively weak. As a result, it is easy to achieve an increase in angle of view.
1<(RL1f+RL1r)/(RL1f-RL1r)<3.5(10)
[0117] In order to obtain more favorable characteristics, it is preferable to use any of 1.1, 1.2, or 1.4, instead of 1 which is the lower limit of Conditional Expression (10). Further, it is preferable to use any of 3, 2.7, or 2.4, instead of 3.5 which is the upper limit of Conditional Expression (10).
[0118] In a case where the second lens is a negative meniscus lens which has a convex surface facing toward the object side, assuming that a paraxial curvature radius of an object side surface of the second lens is RL2f and a paraxial curvature radius of an image side surface of the second lens is RL2r, it is preferable that the imaging lens satisfies Conditional Expression (11).

By not allowing the corresponding value of Conditional Expression (11) to be equal to or less than the lower limit thereof, it is easy to satisfactorily correct astigmatism. By not allowing the corresponding value of Conditional Expression (11) to be equal to or greater than the upper limit thereof, it is easy to satisfactorily correct spherical aberration. Further, by not allowing the corresponding value of Conditional Expression (11) to be equal to or greater than the upper limit thereof, the refractive power of the second lens is prevented from becoming excessively weak. As a result, it is easy to achieve an increase in angle of view.
1<(RL2f+RL2r)/(RL2f?RL2r)<4.5(11)
[0119] In order to obtain more favorable characteristics, it is preferable to use any of 1.05, 1.1, or 1.15, instead of 1 which is the lower limit of Conditional Expression (11). Further, it is preferable to use any of 4, 3.7, or 3.5, instead of 4.5 which is the upper limit of Conditional Expression (11).
[0120] Assuming that a refractive index of the first lens at the d line is NdL1, it is preferable that the imaging lens satisfies Conditional Expression (12). By not allowing the corresponding value of Conditional Expression (12) to be equal to or less than the lower limit thereof, the refractive index of the first lens at the d line is prevented from becoming excessively low. As a result, the imaging lens can be configured without forcibly reducing the absolute value of the curvature radius of the first lens. Thereby, the configuration is advantageous for suppressing occurrence of off-axis aberration, and the configuration is advantageous for achieving reduction in total length of the optical system. By not allowing the corresponding value of Conditional Expression (12) to be equal to or greater than the upper limit thereof, a material of which dispersion is not excessively large can be selected as the first lens. As a result, it is easy to correct lateral chromatic aberration.
1.43<NdL1<1.95(12)
[0121] In order to obtain more favorable characteristics, it is preferable to use any of 1.5 or 1.55, instead of 1.43 which is the lower limit of Conditional Expression (12). Further, it is preferable to use any of 1.84 or 1.72, instead of 1.95 which is the upper limit of Conditional Expression (12).
[0122] Assuming that an open F number of the imaging lens in a state where the infinite distance object is in focus is FNo, it is preferable that the imaging lens satisfies Conditional Expression (13). By not allowing the corresponding value of Conditional Expression (13) to be equal to or less than the lower limit thereof, it is easy to suppress an increase in number of lenses and suppress an increase in size of the lens system while obtaining favorable optical performance. By not allowing the corresponding value of Conditional Expression (13) to be equal to or greater than the upper limit thereof, the angle of view can be widened, or the open F number can be reduced. Therefore, the imaging lens can be used for a wide range of applications, and can be made as a high value imaging lens.
2.5<FNo/sin(?m/2)<6(13)
[0123] In order to obtain more favorable characteristics, it is preferable to use any of 3, 3.3, or 3.5, instead of 2.5 which is the lower limit of Conditional Expression (13). Further, it is preferable to use any of 5.3, 4.7, or 4.3, instead of 6 which is the upper limit of Conditional Expression (13).
[0124] In the imaging lens, assuming that a central thickness of each lens included in the rear group Gr is D, it is preferable that the number of lenses each of which satisfies Conditional Expression (14) and has a positive refractive power is equal to or less than 1. The central thickness is a thickness on the optical axis. By making the number of lenses each of which has a large central thickness that satisfy Conditional Expression (14) equal to or less than 1, a larger number of lenses can be disposed in a limited space in the optical system. Therefore, the configuration is advantageous for achieving reduction in various aberrations. Further, by making the number of lenses each of which has a large central thickness equal to or less than 1, the configuration is advantageous for achieving reduction in weight.
0.155<D/TL(14)
[0125] Assuming that an effective diameter of the object side surface of the first lens is ED, it is preferable that the imaging lens satisfies Conditional Expression (15). By not allowing the corresponding value of Conditional Expression (15) to be equal to or less than the lower limit thereof, the diameter of the first lens is prevented from becoming excessively small. As a result, the configuration is advantageous for ensuring the angle of view and ensuring the amount of peripheral light. By not allowing the corresponding value of Conditional Expression (15) to be equal to or greater than the upper limit thereof, the diameter of the first lens is prevented from becoming excessively large. As a result, it is easy to achieve reduction in size.
1.5<ED/(2?f?sin(?m/2))<5(15)
[0126] In order to obtain more favorable characteristics, it is preferable to use any of 1.7, 1.9, or 2, instead of 1.5 which is the lower limit of Conditional Expression (15). Further, it is preferable to use any of 4.5, 4, or 3.8, instead of 5 which is the upper limit of Conditional Expression (15).
[0127] In the present specification, twice the distance to the optical axis Z from the intersection between the lens surface and the ray passing through the outermost side among rays incident onto the lens surface from the object side and emitted to the image side is the effective diameter of the lens surface. The outer side here is the radial outside centered on the optical axis Z, that is, the side separated from the optical axis Z.
[0128] As an explanatory diagram,
[0129] The above-mentioned preferable configurations and available configurations including the configurations relating to the conditional expressions may be any combination, and it is preferable to optionally adopt the configurations in accordance with required specification.
[0130] For example, in a preferred aspect of the present disclosure, the imaging lens consists of, in order from the object side to the image side, a front group Gf, an aperture stop St, and a rear group Gr that has a refractive power. The front group Gf and the rear group Gr are combined and include at least five negative lenses and at least three positive lenses. A lens closest to the object side in the front group Gf is a first lens as a negative meniscus lens which has a convex surface facing toward the object side. A lens, which is second from the object side in the front group Gf, is a second lens as a negative lens which has a concave surface facing toward the image side. The front group Gf includes at least three negative lenses, which include the first lens and the second lens, and at least one positive lens. With such a configuration, the imaging lens satisfies Conditional Expressions (1), (2), (3), and (4).
[0131] Next, examples of the imaging lens of the present disclosure will be described, with reference to the drawings. The reference numerals attached to the lenses in the cross-sectional views of each example are used independently for each example in order to avoid complication of description and drawings due to an increase in number of digits of the reference numerals. Therefore, even in a case where common reference numerals are attached in the drawings of different examples, constituent elements do not necessarily have a common configuration.

[0135] The table of basic lens data also shows the aperture stop St, and in the column of the surface number of the surface corresponding to the aperture stop St, the surface number and (St) are noted. In the column of R, the sign of the curvature radius of the convex surface facing toward the object side is positive and the sign of the curvature radius of the convex surface facing toward the image side is negative. In the column of D, the symbol DD[ ] is used for each variable surface spacing during focusing, and the object side surface number of the spacing is given in [ ] and is noted. A value at the bottom cell of the column of D indicates a spacing between the image plane Sim and the surface closest to the image side in the table.
[0136] Table 2 shows a focal length f of the whole system, a back focal length Bf, an open F number FNo., and a maximum total angle of view 2?m. [? ] in the cell of the maximum total angle of view 2?m means that the unit thereof is a degree. The values shown in Table 2 are based on the d line. Table 2 shows values in a state where the infinite distance object is in focus.
[0137] Table 3 shows variable surface spacings during focusing. The column of Infinity shows surface spacings in a state where the infinite distance object is in focus. The right cells of the cells of Infinity show absolute values of the imaging magnification in a state where the close object is in focus, and the column thereof shows the variable surface spacings in a state where the close object is in focus.
[0138] In the table of the basic lens data, a mark * is added to a surface number of the aspherical surface, and a numerical value of a paraxial curvature radius is written in the cell of a curvature radius of the aspherical surface. In Table 4, the row of Sn shows surface numbers of the aspherical surfaces, and the rows of KA and Am (m is an integer of 3 or more) shows numerical values of the aspherical coefficients for each aspherical surface. The E?n (n is an integer) in numerical values of the aspherical coefficients of Table 3 indicates ?10.sup.?n. KA and Am are the aspherical coefficients in the aspherical surface expression represented by the following expression.
Zd=C?h.sup.2/{1(1?KA?C.sup.2?h.sup.2).sup.1/2}+?Am?h.sup.m
[0139] Here, [0140] Zd is an aspherical surface depth (a length of a perpendicular from a point on an aspherical surface at height h to a plane that is perpendicular to the optical axis and that is in contact with the vertex of the aspherical surface), [0141] h is a height (a distance from the optical axis to the lens surface), [0142] C is a reciprocal of the paraxial curvature radius, [0143] KA and Am are aspherical coefficients, and [0144] ? in the aspherical surface expression means the sum with respect to m.
[0145] In the data of each table, degrees are used as a unit of an angle, and millimeters (mm) are used as a unit of a length, but appropriate different units may be used since the optical system can be used even in a case where the system is enlarged or reduced in proportion. Each of the following tables shows numerical values rounded off to predetermined decimal places.
