CVD ZnSe Brewster Windows
CVD ZnSe Brewster Windows for polarized CO2 laser cavities. Request size, coating, and drawing review.
Product Overview

Overview
CVD ZnSe Brewster Windows are specified for polarized CO2 laser cavities, beam delivery, and diagnostic 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 the Brewster geometry helps reduce reflection for p-polarized beams without relying only on coating. For this product, the key decision is whether the Brewster-angle window for p-polarized beams, aperture, coating, and mounting conditions match the optical layout.

Application Guidance
Use this product when the optical path requires polarized CO2 laser cavities, beam delivery, and diagnostic paths. Engineers should confirm wavelength, beam diameter or field size, clear aperture, coating target, and mechanical envelope before final drawings are released.
