ZnS Material
Description
ZnS MultiSpectral Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a
water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 microns. This material is
particularly well suited for high-performance common aperture systems that must perform across a broad wavelength
spectrum.
