Product Details

Edmund Optics Designed, Coherent® Manufactured
Premier Grade ZnSe Material
Uncoated or Broadband 8-12µm AR Coating Available

TECHSPEC® Zinc Selenide (ZnSe) Aspheric Lenses are designed to provide diffraction-limited focusing performance for 10.6µm CO₂ lasers. Manufactured from Coherent® Infrared ZnSe material featuring <0.0005 cm^-1 bulk absorption at 10.6µm, these lenses are available uncoated or with a broadband anti-reflection coating providing superior transmission from 8 - 12µm. The precision designs are ideal for integration into laser systems, thermal imaging assemblies, and FTIR devices. TECHSPEC Zinc Selenide Aspheric Lenses feature an irregularity of <λ/20 at 10.6µm, 40-20 surface quality, and <50Å surface roughness.

Notes: II-VI Incorporated is now Coherent Corp.

Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
