What are the applications of cold mirrors?
Entertainment lighting: reduce the heat accumulation of stage or photography lighting to prevent the equipment from overheating.
Projection system protection: prevent infrared rays from damaging the liquid crystal panel or DMD chip.
Microscopy illumination optimization: reduce the risk of thermal damage to the samples.
