Research Electro-Optics Inc. (REO) in Boulder, Colo., is introducing pentaprisms with coatings optimized for military laser applications, such as laser target designation and laser rangefinding, in tough environmental conditions. The REO pentaprisms have dielectric anti-reflection and reflective coatings manufactured using ion beam sputtering (IBS) technology to deliver densified films with strong laser damage characteristics of better than 12 J/cm2 in 20-nanosecond pulses at 1064- nanometer wavelengths, as well as stability and mechanical durability, REO officials say.
REO experts can fabricate pentaprisms from a wide variety of materials for visible and near-infrared spectral ranges. Pentaprism materials include fused silica, optical glasses, silicon, germanium, zinc selenide, and zinc sulfide. Entrance face sizes range from 12 to 25 millimeters. These optics also feature low total wavefront distortion on transmission, laser-grade surface quality, and high deviation accuracy.
