Applications
This CVD ZnSe bi-convex lens is engineered for precision focusing and collimation in 10.6μm CO2 laser systems. Typical use cases include laser cutting, engraving, and welding equipment, thermal imaging optics, non-contact pyrometry, FTIR spectroscopy, and industrial IR sensing modules. For analytical spectroscopic applications, this lens pairs effectively with ZnSe ATR prisms to build complete, high-efficiency optical paths.
Customization & Service
We maintain an extensive in-stock selection of standard IR optics for immediate delivery, including this 25.4mm ZnSe focusing lens. For project-specific requirements, we offer full customization support based on your engineering drawings, with formal technical review prior to every quotation.
