Custom fabricated zinc sulfide (ZnS) windows that are comparable to Cleartran® for use in military vision and thermal imaging systems requiring optics with enhanced clarity, hardness, and scratch resistance have been introduced by Laser Research Optics of Providence, Rhode Island.
Laser Research ZnS Windows are ideally suited 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. Comparable to Cleartran® windows, they are manufactured using Hot Isostatic Pressing (HIP) which provides enhanced clarity, hardness, and scratch-resistance.
Supplied in plano-concave, plano-convex, meniscus, and flat configurations in sizes from 0.5” to 3.0” O.D. or diagonal, Laser Research ZnS Windows are fabricated with typical tolerances of ±0.001” to ±0.005” and thickness to ±0.002”. Featuring λ/4 and λ/10 surfaces and finishes to 10-5 scratch-dig, these windows conform to MIL-PRF-13830.
Laser Research ZnS Windows are priced according to material, configuration, and quantity. Quotations are available upon request.
