CVD ZnSe Flat Windows

Overview

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

Application Guidance

Use this product when the optical path requires CO2 laser protection, thermal imaging, and infrared transmission paths. 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 systems
• IR sensing apertures
• beam delivery paths
• spectroscopy assemblies

Engineering Notes and Inquiry

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

For broader window geometry options, review the ZnSe windows selection path before finalizing the drawing.
