ZnSe Concave-Convex Lenses
ZnSe Concave-Convex Lenses for IR beam shaping. Request size, coating, and drawing review.
Product Overview

Overview
ZnSe Concave-Convex Lenses are specified for IR beam shaping, focusing correction, and compact optical paths. This page focuses on material choice, geometry, coating route, and the engineering information needed before a quotation.
Why This Design Matters
CVD Zinc Selenide (ZnSe) is used because low absorption and high infrared transmission for CO2 laser and thermal imaging optics. For this product, the key decision is whether the concave-convex ZnSe lens geometry, aperture, coating, and mounting conditions match the optical layout.
