ZnS CLEAR - IMPROVED TRANSMITTANCE IN THE VISIBLE SPECTRAL RANGE TO LWIR (LONGWAVE IR)
Polycrystalline Zinc Sulfide (FLIR - Forward Looking Infrared) - in the following referred to as ZnS - is manufactured through applying a chemical vapor deposition (CVD) process.
To produce ZnS CLEAR, ZnS FLIR is treated using a hot isostatic pressing process to eliminate microscopic voids and defects that occur in the regular grade-material.
ZnS CLEAR is commonly used in multi-spectral applications across the visible to infrared region from 0.4 μm – 12 μm.
It is available in large sizes and custom shapes and formats. These can include windows, domes or lens blanks.
