CVD ZnSe Stepped Windows | Dia 25mm, 2.0mm Thickness, Precision IR Optics

Engineered for demanding infrared and CO2 laser applications, our CVD ZnSe stepped windows feature precision-machined step structures on the surface or edge, creating regions with varying thicknesses. Available in single or multi-layer configurations with thickness differences ranging from several microns to several millimeters, these windows deliver consistent optical performance while supporting specialized mounting and beam control requirements. Manufactured from high-quality CVD zinc selenide, these IR windows offer excellent transmittance across the infrared spectrum, making them ideal for precision optical systems.

Technical Specifications

Applications

These stepped ZnSe windows serve critical functions in systems requiring precision mounting alignment and controlled optical path differences. They are widely deployed in CO2 laser resonators and processing equipment, infrared imaging and sensing assemblies, vacuum and pressure viewports, FTIR spectroscopy setups, and industrial beam shaping systems. The stepped geometry simplifies sealed assembly and positional calibration, making them fully compatible with standard CO2 laser optics configurations and custom optical assemblies.
