CVD ZnSe Brewster Windows

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.

Engineering Notes and Inquiry

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