Product Overview
This high-precision CVD Zinc Selenide (ZnSe) Bi-Convex Lens is engineered for high-performance thermal imaging, optical sensors, and IR laser beam focusing systems. Featuring symmetrical radii of curvature (R1 = R2 = 279.80 mm), this optical element delivers minimal spherical aberration in 1:1 imaging setups and conjugate optical paths. With a broad transmission range in the long-wave infrared spectrum and low optical absorption, it serves as a reliable solution for advanced optical engineering applications.
