Regular & Multispectral Zinc Sulfide
(zns, MS zns)

OVERVIEW

Produced using the Chemical Vapor Deposition (CVD) process, Phoenix Infrared provides both multispectral (visible through 3-5 and 8-12 IR ranges) zinc sulfide and regular zinc sulfide. Phoenix Infrared personnel have over 30 years experience with zinc sulfide. Zinc sulfide displays a high level of index of refraction homogeneity and offers imaging uniformity across the 8-12 micron waveband. Zinc sulfide also transmits in the mid-wave IR region, but with higher absorption and scatter as the wavelength increases.

PRODUCTS

For optics producers, we offer SMTY blanks in diameters ranging from 5.5mm to 305mm and thicknesses from 1mm to 15mm. Phoenix Infrared can also offer shaped parts –generated, polished, & coated. We can provide lenses, domes, and other optical components according to customer specifications and drawings. ZnS is also an ideal evaporative source material. Phoenix Infrared supplies ZnS in lump sizes (2-20mm).
