Research Electro-Optics Inc. (REO)Request Info
REO has introduced a range of optics offering multiwavelength operation for military target designation and rangefinding applications. The components deliver a combination of high reflectivity and transmission at multiple wavelength bands (808, 1064 and 1570 nm) while maintaining good wavefront quality in the reflected beam. The optics can accommodate high-reflection or high-transmission properties in the 3- to 5-μm spectral band, enabling common-aperture forward-looking infrared applications. The devices provide a typical high laser damage threshold of >40 J/cm2 for a 20-ns pulse at 1064 nm and exhibit good environmental stability. The optics can be fabricated on a wide range of substrates, including fused silica, CaF2, ZnS, ZnSe, silicon and sapphire, in sizes ranging from 0.5 to 12 in.

Not spherical; an optical element having one or more surfaces that are not spherical. The spherical surface of a lens may be slightly altered so as to reduce spherical aberration. Aspheric surfaces are frequently, but not necessarily, surfaces of revolution about the lens axis.
fused silica
Glass consisting of almost pure silicon dioxide (SiO2). Also called vitreous silica. Frequently used in optical fibers and windows.
Describing a laser that emits simultaneously at more than one wavelength.
