Product Description
Features
1.ZnSe Substrate
2.Broadband AR Coating for the 8-12 μm Range
3.Focal Lengths from -25.4 mm to -200 mm Available
Wuhan Especial Optics' Ø1" Zinc Selenide (ZnSe) Plano-Concave Lenses, which offer high transmission from 0.6-16 μm, are available with a broadband AR coating optimized for the 8-12 μm spectral range deposited on both surfaces. This coating greatly reduces the high surface reflectivity of the substrate, yielding an average transmission in excess of 97% over the entire AR coating range. See the Specs tab for detailed information.
Like all plano-concave lenses, these lenses have negative focal lengths and can be used to diverge collimated beams; in this case, the curved surface should face the source in order to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. ZnSe lenses are particularly well suited for use with high-power CO2 lasers.
