Aspheres for Visible and IR
BOULDER, Colo., Aug. 4, 2010 — Research Electro-Optics Inc. (REO) has introduced a range of high-performance aspheric lenses fabricated from CaF2, ZnSe and ZnS substrates. The lenses offer a combination of benefits for demanding applications that require broadband or multispectral operation from the visible through the infrared, such as military rangefinding and target designation.
Benefits include high surface accuracy of ~λ/4 at 633 nm to achieve small focused spot sizes, low surface roughness of 40 to 50...
