ZnSe Lenses

Overview

ZnSe Lenses are specified for CO2 laser focusing, collimation, beam shaping, and thermal imaging optics. 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 ZnSe infrared lens geometry by drawing, aperture, coating, and mounting conditions match the optical layout.

Application Guidance

Use this product when the optical path requires CO2 laser focusing, collimation, beam shaping, and thermal imaging optics. Engineers should confirm wavelength, beam diameter or field size, clear aperture, coating target, and mechanical envelope before final drawings are released.

• CO2 laser focusing
• infrared collimation
• thermal imaging optics
• beam shaping
• laser processing systems

Engineering Notes and Inquiry

For custom production, send lens type, focal length, diameter, thickness, coating target, and drawing tolerances. OPTOstokes-IROptical can review the drawing, confirm feasible specification ranges, and align the optical component with the downstream assembly.

For adjacent optical paths, compare ZnSe windows when the same material platform is required as a protective or transmissive optic.
