Selection of Dichroic Color Filters
February 24, 2011 – Santa Paula, CA – Abrisa Technologies Dichroic color filter coatings are an excellent alternative to dyed plastics and glass. Unlike plastic color gels that age and breakdown relatively quickly during use, dichroic filters from Abrisa Technologies are designed to stand up to the heat and UV energy in high energy light sources.
Dichroic filters have the advantage of reflecting unwanted light instead of absorbing the energy, allowing dichroic filters to be used with much higher intensity light sources. Used in a variety of applications, Abrisa Technologies’ dichroic filters can be found in architectural lighting, entertainment lighting, and in science and engineering applications.
Abrisa Technologies has over 160 different colors of dichroics in stock. The long lasting filters can be used in temperatures up to 900°F, and come standard at 1.75mm (.069) thick unless noted on Borofloat®. In addition to dichroic colors, Abrisa Technologies offers a host of dichroic color correction filters as well as solid colored glass which can be heat treated up to 6” in diameter for added resistance, at 1/8” thick.
Specialty and custom filters can be supplied in a range of thicknesses:
- UV blockers – block virtually all transmission below 400nm
- Hot mirrors – reflect infrared heat, while passing visible light
- Cold mirrors – reflect visible light while passing infrared
- UV blacklite – passes UV and blocks visible light
- Neutral density filters – reduces light transmission
