Custom fabricated zinc sulfide (ZnS) optics that are water-clear with minimum scatter and provide high transmission capabilities across a broad wavelength spectrum for a variety of military applications are being introduced by Laser Research Optics.
Laser Research ZnS Optics are ideal for single aperture, high performance multi-spectral systems that must perform over a broad wavelength spectrum from 0.4 to 12µm. Ideally suited for military and homeland security thermal imaging systems, they can be supplied as lenses and windows in plano-convex, -concave, meniscus, and flat configurations.
Manufactured using hot isostatic pressing, which provides enhanced clarity, hardness, and scratch resistance, Laser Research ZnS Optics are offered in sizes from 0.5" to 3" O.D. or diagonal 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, they conform to MIL-PRF-13830.

Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
