A reflective module disclosed in an embodiment of the invention includes a holder having an inclined bottom surface and both side walls of the inclined bottom surface; a reflective member disposed on the holder; and an adhesive bonding the reflective member to the holder, wherein the reflective member includes an incident surface, an exit surface, and a reflective surface opposite to the bottom surface, and the holder has a first surface facing both side surfaces of the reflective member. and a second recess portion, wherein the adhesive includes: a first adhesive adhered to lower portions of each side of the reflective member within the first and second recess portions; and a second adhesive adhered to an upper portion of each side surface of the reflective member, and the first and second adhesives may be of different types.

Embodiments described herein relate to camera modules which include a prism, and a lens assembly and image sensor positioned adjacent to a common side of the prism. The camera module may be configured such that the light enters the prism (e.g., from the lens assembly) via a first surface and exits the prism (e.g., directed to the image sensor) via the same, first surface. The prism may be operable to move with respect to both the lens assembly and the image sensor via an actuator. The prism may include opaque masks extending from a second surface that is opposite the first surface and into the body of the prism. The structure described can help reduce the overall package size of the camera module due to the configuration of the prism.

A spherically mounted retroreflector comprising an optic inlay, the optic inlay comprising a retroreflector having a vertex and an axis of symmetry, and a carrier having an at least partly spherical outer surface and a cavity, wherein the optic inlay is arranged in the cavity, and wherein the at least partly spherical outer surface has a sphere center, which sphere center coincides with the vertex, wherein the optic inlay is connected to the carrier. The optic inlay comprises a coupling portion, and the spherically mounted retroreflector comprises a coupling element arranged between the optic inlay and the carrier.

An optical element driving mechanism including a fixed part, a movable part, a first driving assembly, a second driving assembly, and a magnetic-permeable element is provided. The fixed part includes a bottom. The movable part holding an optical element with an optical axis is movable relative to the fixed part. The first driving assembly includes a first magnetic element and a first coil arranged along a first direction. The second driving assembly includes a second magnetic element and a second coil arranged along the first direction. The first driving assembly and the second driving assembly drive the movable part to move relative to the fixed part along a second direction and a third direction, respectively. The first direction, the second direction, and the third direction are different. When viewed in the optical axis, the first driving assembly at least partially overlaps the second driving assembly.

A target object providing a large angular incidence range for retroreflection and a reduced amount of interfering reflections. The target object is configured to provide a 360 all-around retroreflection about a vertical axis and 45 angular incidence range from the horizontal. According to one aspect, the target object comprises eight triple prisms arranged around the arrangement axis in such a way that their contour embeds in an octahedral shape, wherein four of the eight triple prisms are arranged to embed in a first pyramidal body and other four of the eight triple prisms are arranged to embed in a second pyramidal body. Each of the first and the second pyramidal bodies comprises a pyramid base and four lateral surfaces, wherein the pyramid bases of the first and the second pyramidal bodies are arranged parallel to each other.

The present disclosure provides an optical lens module. By assembling a first lens barrel, an optical folding element and a second lens barrel, the optical lens module can be miniaturized, image quality of the optical lens module in a compact assembly space can be increased, and the size of a light passage opening of a display panel module can be reduced so as to increase consistency of a display area.

An optical unit has an optical element reflecting light between intersecting first and second directions, and a holder. The holder includes a holder body extending in a third direction intersecting the first and second directions, and a pair of surface portions extending from the holder body in an intersection direction intersecting the third direction. The optical element is arranged between the surface portions. At least one surface portion has an inner surface facing the optical element, an end surface connected to an edge of the inner surface in an intersection direction, and a concave portion arranged astride the inner and end surfaces and recessed in the intersection direction from the end surface. The concave portion accommodates an adhesive member bonding the optical element with the holder. The length of the concave portion along the end surface is greater than the depth of the concave portion in the intersection direction.

An optical unit with a runout correction function includes a reflection member, a camera module having a lens and an image pickup element, a holding member that rotatably holds the reflection member and also holds the camera module, and a fixing member that rotatably holds the holding member. A second rotation mechanism rotates the reflection member held in the holding member with an optical axis direction, which is a direction of an optical axis of the lens, as an axis direction of the rotation and is capable of runout correction in a yaw direction. In the optical unit with a runout correction function, when the runout correction in the yaw direction is performed, the image pickup element held in the holding member is rotated together with the reflection member with the optical axis direction as the axis direction of rotation.

A reflective module includes a housing having an internal space, a rotation guide disposed in the internal space and configured to rotate about a first axis, relative to the housing, a reflective member holder including a reflective member and supported by the rotation guide, and a damper protruding from a bottom surface of the housing toward the internal space, wherein the damper includes a first damper disposed adjacently to the first axis, and a second damper disposed in a position spaced apart from the first damper.

An aperture unit having an optical axis is provided, which includes a fixed portion having a first surface and including a protrusion formed on the first surface, a guiding element movably connected to the fixed portion and including a through hole, a first blade movably connected to the guiding element and the fixed portion, and a driving assembly use for driving the guiding element to move for moving the first blade. The optical axis passes through the through hole. The first surface has a first accommodating space having a recessed structure to accommodate the guiding element, and the protrusion extends toward the first blade.
