Attenuation Unit 90

Line

The attenuation units are add-ons to the LaserDec CL Beam Profilers. They are based on a zinc selenide (ZnSe) beam splitter and can be mounted in four positions on the LaserDec aperture. They are designed for a 45 angle of incidence and can be used up to intensities of 5kW/cm2.

Attenuation Unit 90 Reflection

The absorbed heat is dissipated by cooling water whereby thermal lens effects are eliminated. The water-cooling allows the utilization of lasers up to powers of 3kW. To avoid interference patterns the beam splitter is designed with a wedge angle.
