IR Spherical Lenses
Jun 2011Research Electro-Optics Inc. (REO)Request Info
For military applications, REO has introduced a range of infrared
spherical lenses. These include forward-looking infrared imagers that also incorporate
laser lines as well as other IR laser-based systems, such as those used in laser
targeting and IR countermeasure applications. The lenses are fabricated from a variety
of substrate materials, including CaF2, ZnS, ZnSe, Ge, Si and GaAs, enabling operation
over the 3- to 14-μm spectral range. Component diameters are available from
0.25 to 10 in., and typical surface flatness for the optics is λ/10 at 633 nm. Infrared
optics of this type often are used in military systems in which environmental stability
and coating durability are critical, and/or where multispectral operation is required.
The company can customize the lenses to facilitate assembly and mounting.
