[IMSAI Guy] presents for your viewing pleasure, a nice video on the topic of optical filters and mirrors. (Video, embedded below) The first optical device is a simple absorption filter, where incoming ...

Interference filters are frequently employed in transmissive configurations where the light passes through the filter to produce a specific effect (band-pass, long-pass, short-pass, among others).

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

IT is not generally known that by using ‘Polaroid’ filters of sufficient size (1½ in. to 2 in. diameter), optical interference-figures afforded by crystals in convergent polarized light—most difficult ...

Spectrogon manufactures optical interference filters, thin film coatings, and holographic diffraction gratings. The filters are used in several applications such as medical, process industry, thermal ...

Flow cytometry is a high-throughput method of cell analysis wherein live cells are passed in single file by a series of lasers and detectors. The degree of scattering experienced by the laser light ...

Imaging equipment to observe the earth from space provides data for various uses. Wavelength-discriminated imaging at a considerable distance from the earth’s surface is the basic idea behind optical ...
