ZnSe Windows

Overview

ZnSe Windows are specified for CO2 laser protection, infrared transmission, and thermal imaging apertures. 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 flat or custom infrared window, aperture, coating, and mounting conditions match the optical layout.

Key Specification Summary

Application Guidance

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

• CO2 laser protective windows
• thermal imaging windows
• IR sensing apertures
• beam delivery protection
• spectroscopy windows

Engineering Notes and Inquiry

For custom production, send diameter, thickness, clear aperture, coating target, and mounting environment. OPTOstokes-IROptical can review the drawing, confirm feasible specification ranges, and align the optical component with the downstream assembly.

For assemblies that also require focusing or collimation, compare ZnSe lenses within the same infrared material family.
