Infrared Spherical Lenses for

nnnn

Demanding Military Applications

nnnn

These spherical lenses are specifically designed to meet the needs of

nnnn

demanding applications throughout the infrared. These include high

nnnn

performance FLIR imagers that also incorporate laser lines, as well as

nnnn

other IR laser-based systems, such as used in laser targeting and IR

nnnn

countermeasure applications. REO fabricates these lenses from a variety

nnnn

of substrate materials, including CaF2, ZnS, ZnSe, Ge, Si, GaAs, thus

nnnn

enabling operation over the 3 urn to 14 urn spectral range. Component

nnnn

diameters are available from 6 mm to 250 mm, and typical surface

nnnn

flatness for these optics is A/10 (at 633 nm).

nnnn

Infrared optics of this type are often used in military systems in which

nnnn

environmental stability and coating durability are critical, and/or where

nnnn

multi-spectral operation is required. REO employs advanced plasma

nnnn

source (APS) coating technology in order to deliver highly densified thin

nnnn

films which exhibit superior resistance to environmentally-induced damage or performance degradation.

nnnn

Plus, APS technology also enables precise control over coating layer stress, which allows good control over

nnnn

part distortion on high aspect ratio parts. This enhances the stability of the physically thick films often

nnnn

required for multi-wavelength operation in the IR.

nnnn

REO can also readily customize these lenses with a variety of features to facilitate assembly and mounting,

nnnn

especially in space constrained systems. These features include holes, slots and polished mounting surfaces

nnnn

(for o-ring contacting). REO also provides abrasive jet machining (AJM) services to roughen selected areas of

nnnn

lens edges so as to provide a more compliant surface for adhesive bonding.
