Calflex™ – IR blocking filter

Some designs of entertainment, medical, and architectural lights require additional heat reduction. In entertainment lighting, infrared filtering keeps performers in the spotlight as cool as possible. Optics Balzers’ Calflex™ filters reflect infrared radiation while transmitting visible light and allow for varying emission behaviors of different light sources. Calflex™ filters allow maximum transmission in the visible waveband without changing the colorimetric characteristics of the light source.
