ZnSe Plano convex Lens

Zinc Selenide (ZnSe) plano-convex (PCX) lenses are designed for focusing or collimation applications in the mid-wave and long-wave infrared spectroscopy. These lenses have a volume absorption coefficient of <0.0005cm-1 at 10.6µm wavelength and are available uncoated or with a variety of broadband antireflection coating options. The 8-12µm coating is ideal for use with CO2 lasers and thermal camera applications, while the dual-band 3-12µm coating is suitable for hyperspectral applications.


ZnSe Plano convex LensDescription

The ZnSe plano-convex lens has an irregularity of <λ/20 at 10.6µm wavelength, a surface quality of 40-20, and a surface roughness of <50Å. Three diameter options are available, with effective focal lengths ranging from 12.7mm to 200mm.
