Research Electro-Optics (REO) Inc.’s high-performance aspheric lenses are fabricated from CaF2, ZnSe and ZnS substrates. The lenses offer a combination of benefits for applications that require broadband or multispectral operation from the visible through the infrared, including military rangefinding and target designation. Benefits include high surface accuracy of approximately λ/4 at 633 nm to achieve small focused spot sizes; low surface roughness of 40 to 50 Å rms for minimal scatter and loss; and sophisticated, multilayer thin-film coatings. The coatings offer multispectral performance and a high-laser-damage threshold and are produced with a densified structure to yield good environmental stability. These features can be maintained even with unusually thin lens profiles, so the aspheres can deliver important weight advantages for portable, field and airborne applications. The lenses are fabricated and coated in high volume on a custom basis.
