Dichroic Filters: Filters encased in glass for colour printing that are built into an enlarger head. The colour balance of dichroic filters is set by adjusting dials, instead of moving individual filters.
dichroic filter
A light producing mechanism which concentrates and directs visible light but not infrared radiation (heat). Used in movie and multimedia production, and in some scanners. See scanner.

Dichroic Filters Most photographic filters use colored dyes that absorb certain wavelengths and allow others to be transmitted. Such filters do not begin and end transmission at precise wavelengths.
Dichroic Dichroic filters are interference filters at an angle of incidence of light of 45°. The transmissivity and reflectivity of dichroites depend on a specific wavelength of light.
A hot mirror is a specialized dielectric mirror, a dichroic filter, often employed to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass.
Dichroic RGB filters don't lose light, they spilt it very efficiently between R, G and B. Lossy colored filters absorb all colors, except for the color they pass. Dichroic filters are mirrors which reflect one color and pass the other colors along ...
