UV/IR-Blocker and UV-Blocker

High UV/IR Rejection / High UV Rejection

Materion Balzers Optics UV/IR-Blocker effectively remove damaging ultraviolet and unwanted infrared radiation produced by broadband light sources. A dielectric oxide coating design provides excellent transmission over the entire visible spectrum, without distorting the spectral emission of the light source. Filters are optimized for metal halide lamps and are particularly well suited for use in applications where high thermal loads exist. Where infrared raditation is not critical use the Materion Balzers Optics UV-Blocker.
