CVD ZnSe 60° Equilateral Prisms | 0.6–21μm Infrared Transmission

CVD ZnSe 60° Equilateral Prisms | 0.6–21μm Infrared Transmission

Chemical vapor deposited (CVD) polycrystalline zinc selenide equilateral prisms are precision-engineered for infrared beam steering, wavelength separation, and spectral dispersion applications. With a wide transmission window spanning 0.6 to 21 μm and optimized performance at 10.6 μm, these 60° prisms deliver consistent optical performance for CO₂ laser systems and mid-infrared analytical instruments. Manufactured to tight angular and dimensional tolerances, they integrate seamlessly into existing optical assemblies alongside our full line of zinc selenide optics. Standard 20 mm units are held in stock for fast delivery, while custom geometries and coating options are available for dedicated project requirements.

Technical Specifications

Applications

ZnSe equilateral prisms serve as core beam control components across industrial, scientific, and defense infrared systems. They are most commonly deployed in 10.6 μm CO₂ laser material processing lines for beam deviation and wavelength tuning, and in Fourier-transform infrared (FTIR) spectrometers for spectral dispersion. Additional use cases include mid-infrared gas sensing instruments, thermal imaging calibration setups, and IR spectroscopy research platforms. These prisms are often paired with precision infrared lens assemblies to build complete, aligned optical trains for LWIR and MWIR systems.

Customization & Service

Standard 20 × 20 × 20 mm 60° equilateral prisms are maintained in stock for immediate shipment, supporting rapid prototyping and urgent production replenishment. For application-specific requirements, we offer full drawing-based customization, including custom aperture sizes, angular tolerances, surface finish grades, and anti-reflective or protective coatings. All parts are manufactured under ISO 9001-aligned processes, with pre-shipment inspection covering dimensional accuracy, surface quality, and angular deviation. Every custom order receives a formal engineering review before quotation to ensure material, tolerance, and coating selections match your system performance targets. The prisms are mechanically compatible with our standard IR windows and beam control components for simplified system integration.
