CONVERSION FILTERS

POSSIBILITIES OF COLOR DESIGN

Absorption-free, dichroitic filters serve the purpose of modifying the color temperature of light sources. The non transmittable radiation is separated by reflection. In addition to our standard filters, it is also possible to produce filters which are individually adaptable to lamps currently in use. For high intensity applications conversion filters can also be applied to glass ceramics.
