Product Overview
ZnSe Attenuator 5000nm T=40%+/-5% for IR Lasers
Designed for mid-infrared beam management, this zinc selenide (ZnSe) attenuator delivers accurate intensity reduction with a targeted transmission of 40% (+/-5%) at 5000 nm. Built with high-purity CVD substrate, it provides exceptional optical flatness, low bulk absorption, and high damage resistance, making it ideal for high-power laser beam profiling, thermal sensing calibration, and optical attenuation in precision laboratory environments.
