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.
