	Attenuation Unit 90°



	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.


	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.
