The present disclosure discloses a camera optical lens. The camera optical lens including, in an order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens is made of plastic material, the second lens is made of glass material, the third lens is made of glass material, the fourth lens is made of plastic material, the fifth lens is made of plastic material, the sixth lens is made of plastic material, and the seventh lens is made of plastic material. The camera optical lens further satisfies specific conditions.

A tunable lens includes a soft transparent polymer layer whose shape (optical profile) is dynamically modified by actuation of one or more piezoelectric actuators or shaping/reshaping of a transparent piezoelectric layer with a plurality of actuation zones on it. Through control of the actuation voltage a particular shape corresponding to a desired focal distance is obtained. Thus, spherical or aspherical reshaping of the tunable lens may be accomplished through the transparent piezoelectric layer.

An anamorphic objective having a relatively small anamorphic factor but with relatively pronounced residual anamorphic artifacts is formed by reducing the anamorphic factor with anamorphic lens elements located on the image side of the aperture stop. The lens section on the object side of the aperture stop must therefore have a relatively large anamorphic factor, and this creates the desired residual anamorphic artifacts. The disclosed anamorphic objective is suited either to an integrated optical design or to a modular approach in which the anamorphic factor reduction optics are connected as a removable attachment to an independently well-corrected anamorphic optical system. The anamorphic objective has a relatively small anamorphic squeeze ratio while simultaneously producing relatively large residual anamorphic characteristics.

An anamorphic optical element and an adjustment mechanism for selectively rotating the optical element either around an axis substantially in a vertical direction, an axis substantially in an optical axis direction, an axis substantially in a plane formed by the vertical direction and the optical axis direction, or combination of axes thereof is used to vary a vertical separation between two or more spots.

An image recording device having a projected viewfinder is described that projects individual, or multiple sets of synchronized framing beams onto a target image that are coaxially aligned with the field of view of the camera. The set of framing beams is projected onto the target image beyond the scope of the field of view being recorded by the image recording device but still within the field of vision of the operator of the device. In this way, the operator of the image recording device will be able to clearly see the framing beams identifying the limits of the recorded areas, while not having any portion of the field of view of the image recording device obscured by the framing beams themselves.

An optical system includes a first optical system to transmit image light emitted from an image display element that displays an image to form an intermediate image of the image light; an optical component having a partially reflective surface having functions of transmitting and reflecting the image light; a second optical system to reflect, to the optical component, the image light transmitted through the first optical system and transmitted through or reflected by the partially reflective surface of the optical component: and a light guide member to guide the image light reflected by the second optical system and transmitted through or reflected by the partially reflective surface of the optical component.
