Heat Protection Filter Medical Lighting

Many light sources not only deliver the desired illuminance but also an undesired high intensity radiation below and beyond the visible part of the spectrum (e. g. halogen, xenon). Especially an intensive heat radiation is perceived to be disturbing in most working environments. Materion Balzers Optics family of Calflex™ heat protection filters effectively removes damaging radiation from illumination systems with broadband light sources. These filters combine extremely high transmission in the visible range and a sharp transmission to block transition in the IR. Several types of Calflex™ products are available to balance cost versus performance. The IR-blocking range of the products can be designed by taking the specific illumination source into account.
