ZnS Optics Water-Clear Windows, Lenses & Domes
Offered as windows, lenses, and domes, Zinc sulfide optics transmit over a broad wavelength spectrum from 0.45 to 12 µm. They can be custom fabricated for use in military applications requiring a broad wavelength spectrum and exceptional fracture strength.
ZnS Optics are water clear and are offered as windows, lenses, and domes. Manufactured using Hot Isostatic Pressing (HIP) which provides enhanced clarity, hardness, and scratch resistance, they conform to MIL-PRF-13830 and are suitable for many military vision system applications.
They can be fabricated in sizes from 0.5 to 3-in. (13 to 76 mm) O.D. or diagonal, with typical tolerances of ±0.001 to ±0.005-in. (25 to 127 µm) and thickness to ±0.002 in. (51 µm) Knoop Hardness is 150 to 165 kg/mm2, Rupture Modulus is 69 MPa, and they feature ?/4 and ?/10 surfaces and finishes to 10-5 scratch dig.
