IR and Broadband Optics feature plano convex, concave, and meniscus configurations with finishes to 10-5 scratch-dig. Fabricated from zinc selenide, zinc sulfide, and germanium, silicon, calcium-, and magnesium fluoride for transmission out to 20 µm, these custom fabricated optics are available with or without A/R coatings. Produced in prototype to production quantities, the IR and Broadband Optics can be supplied in sizes from 0.25 in. to 5.0 in. O.D. or diagonal, with ۪.005 in. tolerances and thickness to ۪.002 in., and conform to MIL-PRF-13830.
