A 1978 study by the FAA looked at the "aeromedical" implications of the X-chrom lens, finding that the lenses increased scores in pseudoisochromatic plates without increasing performance in practical tests (e.g. aviation signal light gun test). [4] They subsequently banned the use of X-chrom lenses during tests.
A case history using the X-Chrom lens for a rod monochromat is reported [60] and an X-Chrom manual is online. [61] Tinted glasses (e.g. Pilestone/Colorlite glasses) apply a tint (e.g. magenta) to incoming light that can distort colors in a way that makes some color tasks easier to complete.
EnChroma lenses are composed primarily of an optical notch filter that selectively filters wavelengths of light in the part of the spectrum where the M- and L-opsin sensitivities overlap, namely 530-560 nm, thereby removing light that excites both opsin types and decorrelating the signals between the M- and L-cones.
The OSLO software is used by scientists and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems. It is also used for simulation and analysis of optical systems using both geometrical and physical optics. In addition to optical design and analysis, OSLO provides a complete technical software ...
Telephoto lenses using diffractive elements to minimize chromatic aberration are commercially available from Canon and Nikon for interchangeable-lens cameras; these include 800mm f/6.3, 500mm f/5.6, and 300mm f/4 models by Nikon (branded as "phase fresnel" or PF), and 800mm f/11, 600mm f/11, and 400mm f/4 models by Canon (branded as ...

A gradient-index lens with a parabolic variation of refractive index (n) with radial distance (x).The lens focuses light in the same way as a conventional lens. Gradient-index (GRIN) optics is the branch of optics covering optical effects produced by a gradient of the refractive index of a material.
Zemax is a software program used for designing and simulating optical systems. It is widely used in the field of optics and photonics for designing and analyzing the performance of lenses, cameras, telescopes, microscopes, and other optical systems. With the software, the behavior of light interacting with various optical components can be ...
