Zinc Sulfide (ZnS) windows that provide enhanced clarity and hardness and can be custom fabricated for military vision and thermal imaging systems requiring optics that perform over a wide wavelength spectrum have been introduced by Laser Research Optics of Providence, Rhode Island.
Laser Research ZnS Windows are manufactured using Hot Isostatic Pressing (HIP) which provides enhanced clarity, hardness, and scratch-resistance. Comparable to Cleartran®, they are designed for use in single aperture, high performance multispectral military vision and thermal imaging systems that must perform over a broad spectrum from 0.35 to 12 microns.
Fabricated with typical tolerances of ±0.001” to ±0.005” and thickness to ±0.002”, Laser Research ZnS Windows are supplied in plano-concave, plano-convex, meniscus, and flat configurations in sizes from 0.5” to 3.0” O.D. or diagonal. Conforming to MIL-PRF-13830, these windows feature λ/4 and λ/10 surfaces and finishes to 10-5 scratch-dig.
Laser Research ZnS Windows are priced according to configuration, and quantity. Quotations are available upon request.
