Technical Information
|
Our Color Process Filters separate the visible light spectrum into primary color regions. These color regions are selectively transmitted or reflected with high efficiency, and virtually without absorption, allowing the filters to be used in both the reflective and the transmissive modes. These Filters are commonly used in photography, image analysis, color video, special lighting effects, color correction and studio and architectural lighting. Our Color Process are made with dielectric hard coatings deposited on heat resistant borosilicate glass substrates, producing highly stable and durable optics that exceed the adherence, abrasion, hardness and durability standards of Mil-C-675A and Mil-M-13508C.
