ZnS

ZnS is a very important optical crystals applied in IR waveband. Transmitting range of CVD ZnS is 8um-14um, high transmittance, low absorption, ZnS with multi-spectrum level by heating etc. static pressure technics has improved the transmittance of IR and visible range.

Applications:Optics,electronics, photoelectronic devices.

Features:Excellent optical uniformity, resisting acid-base erosion,stable chemical performance. High refractive index,high refractive index and high transmittance within visible range.
