ZINC SULFIDE WINDOWS MULTI-SPECTRAL FOR HOSTILE ENVIRONMENTS

optics for hostile environments

Custom fabricated ZnS windows for a wide range of military applications requiring mechanical resistance to hostile environments in the VIS and IR have been introduced by Laser Research Optics of Providence, Rhode Island.

Laser Research ZnS Windows are ideally suited for single aperture, high performance multi-spectral systems from 0.35 to 14 microns that will be exposed to hostile environments. They can be supplied in plano-concave, plano-convex, meniscus, and flat shapes in sizes from 0.5” to 3.0” O.D. or diagonal for use in military vision and thermal imaging systems.

Comparable to Cleartran® windows, Laser Research ZnS Windows are manufac-tured using Hot Isostatic Pressing (HIP) which provides enhanced clarity, hardness, and scratch resistance. Knoop Hardness is 150-165 kg/mm2, Rupture Modulus is 69 MPa, and they feature λ/4 and λ/10 surfaces and finishes to 10-5 scratch dig. These ZnS windows conform to MIL-PRF-13830.

Laser Research ZnS Windows are priced according to configuration, and quantity. Quotations are provided upon request.
