Product Overview
Engineered for high-power CO2 laser systems, thermal imaging, and LWIR spectrometry, this high-precision ZnSe plano-convex lens provides exceptional transmission across the long-wave infrared spectrum. Manufactured from optical-grade chemical vapor deposition zinc selenide (CVD ZnSe), it delivers low bulk absorption at 10.6 µm and minimal chromatic aberration, making it an essential component among premium optical components for beam focusing and collimation.
When selecting high-performance elements for system integration, engineering teams often combine these lenses with specialized infrared optical filters to optimize signal-to-noise ratios in thermal sensing and spectroscopy applications.
