Dichroic Laser Beam Combiners

Low absorption filters for laser beam combining

High efficiency by combining of laser source is a key feature of the dichroic laser beam combiners made by Materion Balzers Optics. They are produced by hard sputtering coating technology. Therefore, lowest absorption values can be offered. The dichroic laser beam combines are made for an angle of 45° of incidence. Dimensions and wavelengths can be customized. Steep edges between transmission and reflection band can be guaranteed.

Benefits

• Low absorption value
