This was first introduced in mass production by the Univis Lens Co. of Dayton, OH. in 1926. [11] In 1935, Courmettes went on to patent the Tilted Bifocal Lens, [12] in 1936, a method of grinding two prescriptions simultaneously on that Tilted Bifocal Lens, [13] and in 1951, the Cataract Bifocal Lens.

Camera lenses use a wide variety of designs because of the need to balance and trade off different requirements: angle of view (i.e. focal length in relation to the film or sensor size), maximum aperture, resolution, distortion, color correction, back focal distance, and cost. Celor lens; Chevalier lens; Cooke Triplet; Double-Gauss lens ...
A lenticular lens is an array of lenses, designed so that when viewed from slightly different angles, different parts of the image underneath are shown. [ 1 ] [ 2 ] [ failed verification – see discussion ] The most common example is the lenses used in lenticular printing , where the technology is used to give an illusion of depth, or to make ...
Designing a lens that reproduces colour accurately is also important as is the production of an evenly lit and sharp image over the whole of the film or sensor plane. For the lens designer, achieving these objectives will also involve ensuring that internal flare, optical aberrations and weight are all reduced to the minimum whilst zoom, focus ...
The very first version of the software was written in DOS and consisted of little more than a UI framework for quickly chaining together the output of pre-existing batch files and utilities. eyeon Software Inc. was formed specifically to commercialize Fusion, and all operations relating to the software were moved to Toronto, Ontario, Canada.
Lens finders are camera format specific and require the lenses that will be used in production. They can only be viewed by one individual at a time. Variations exist for different lens mounting systems, most typically Arri PL , Arri LPL, Panavision PV mount , Panavision SP70 and Mitchell BNCR mounts .
A burning apparatus consisting of two biconvex lens. A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.
First known film is the first film (not including tests) made with the format and intended for release. Negative gauge is the film gauge (width) used for the original camera negative. Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case ...
