The Mamiya RZ67 is a professional medium format single-lens reflex camera manufactured by Mamiya.There are three successive models: the RZ67 Professional (released in 1982), RZ67 Professional II (released in 1993) and RZ67 Professional IID (released in 2004).
In microscopy, NA is important because it indicates the resolving power of a lens. The size of the finest detail that can be resolved (the resolution) is proportional to λ / 2NA , where λ is the wavelength of the light. A lens with a larger numerical aperture will be able to visualize finer details than a lens with a smaller numerical ...
Angle-supported intraocular lenses are a special kind of intraocular lens that can be implanted surgically into the anterior chamber of the eye. These lenses are called angle-supported because the footplates of the lens rest in the irido-corneal angle .
[6] A wide-angle lens has a shorter focal length and includes more of the viewed scene than a normal lens; a telephoto lens has a longer focal length and captures a small portion of the scene, making it seem closer. Lenses are not labeled or sold according to their angle of view, but rather by their focal length, usually expressed in millimeters.
An axicon is a specialized type of lens that has a conical surface. An axicon transforms a laser beam into a ring shaped distribution. [1] They can be convex or concave and be made of any optical material. The combination with other axicons or lenses allows a wide variety of beam patterns to be generated.
A lens may be considered a thin lens if its thickness is much less than the radii of curvature of its surfaces (d ≪ | R 1 | and d ≪ | R 2 |).. In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces.

A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance between an object being imaged and the lens, or the distance between the image plane and the lens, or both, and ...
