Propery of Zinc Sulfide
Broadband Transmission Wavelength
ZnS Material including CVD ZnS and Multispectral ZnS, CVD ZnS transmission range from 3-5um and 10-14um, Average of Transmittance 50%, Multispectral ZnS Average transmission 70% in the wavelength 0.37-12um.
High Refractive index and high Purity
ZnS is a high index material 2.65, it’s suitable for optical components, high purity can reduce the light scatter and loss, improve the transmission efficiency and image quality of optical system.
Resists radiation
ZnS has a property of resist radiation damage from high energy light, extend the service life of optical components.
Thermal and chemical stability
High temperature conditions in high power laser systems to ensure the stability and reliability of the optical system.
