The design of photographic lenses for use in still or cine cameras is intended to produce a lens that yields the most acceptable rendition of the subject being photographed within a range of constraints that include cost, weight and materials. For many other optical devices such as telescopes, microscopes and theodolites where the visual image ...
Rodenstock Photo Optics traces its origins to a mechanical workshop founded in 1877 by Josef Rodenstock and his brother Michael in Würzburg, Germany. The company relocated to Munich by 1884 and became an important manufacturer of both corrective lenses for glasses and camera lenses by the early 1900s. These two lines began to diverge in the ...
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically . There is no major difference in principle ...
Not to be confused with Fresnel lens. A flat lens is a lens whose flat shape allows it to provide distortion-free imaging, potentially with arbitrarily-large apertures. [1] The term is also used to refer to other lenses that provide a negative index of refraction. [2] Flat lenses require a refractive index close to −1 over a broad angular range.
Pinhole glasses are a type of corrective glasses that do not use a lens. Pinhole glasses do not actually refract the light or change focal length. Instead, they create a diffraction limited system, which has an increased depth of field, similar to using a small aperture in photography. This form of correction has many limitations that prevent ...
Simple lens designs. Simple lenses are lenses consisting of a single element. Lenses in this section may overlap with lens designs in other sections, for example the Wollaston landscape lens is a single element and also a camera lens design. Basic types. Biconcave lens; Biconvex lens; Convex-concave lens; Plano concave lens; Plano convex lens ...
