  • PPG Awarded Follow-On Contracts for Missile Warning Sensors
Oct 2005
NORTHVALE, N.J., Oct. 3 -- Photonic Products Group Inc. announced that its Inrad business unit, which specializes in crystal-based optical components and devices, laser accessories and instruments, has been awarded a series of follow-on production contracts in recent months from ATK Missile Systems' Clearwater, Fla., facility for over 5500 of two types of ultraviolet (UV) waveband optical filter elements for their upgraded AN/AAR-47 missile warning systems.

According to PPG, the filters are specialty optical components made from high-purity and high-uniformity single crystals of a proprietary material which absorbs all wavelengths except those in the UV region of the electromagnetic spectrum. These synthetic single crystals are key optical components of airborne electro-optical missile warning sensors.

ATK Missile Systems, a division of Alliant Techsystems, is the developer and prime contractor for production of this warning system for protection of low and slow-flying aircraft from a variety of missiles. In low-rate production since 2002 and in high-rate production at present, these components will be incorporated into systems for US Navy, US Air Force and US allies' aircraft. The dollar value of the contract was not disclosed.
