Product Family Description

  • Edmund Optics Designed, II-VI 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 II-VI 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.
