Precision 10.6 µm IR Focus Lens
ZnSe Bi-Convex Lens Dia 25.4mm FL 75mm Uncoated
High-precision uncoated ZnSe bi-convex lens (Dia 25.4mm, FL 75mm) for 10.6 µm CO2 laser systems. In-stock & custom options available at iroptical.
Product Overview
This uncoated Zinc Selenide (ZnSe) bi-convex lens is engineered for high-performance thermal imaging and CO2 laser applications operating at the 10.6 µm design wavelength. Featuring symmetrical double-convex surfaces, it offers balanced refraction, making it ideal for beam focusing, relay systems, and spatial filtering. Manufactured with optical-grade CVD ZnSe, this lens guarantees low insertion loss, high optical homogeneity, and resistance to thermal shock in demanding high-power laser environments.
