Abstract

Infrared (IR) imaging systems are a critical component of military aircraft operations for navigation, surveillance, and target acquisition. A limiting feature in the readiness and life-cycle costs for such IR systems is the durability of the exposed optical window in the harsh land and sea environments associated with military operations. The Air Force Research Laboratory, Materials Directorate, has been conducting a program to develop a high durability, repairable JR window to both extend the operation life-cycle of the transparencies and to permit the reuse of the optical materials for significant cost reductions. The development effort is focused on a composite JR window composed of a highly JR transparent base material with a removable durable bonded cladding for erosion and abrasion protection. The development activities have included evaluation and selection of the optical materials, assessment of high durability coatings, refinement of the optical adhesive and bonding process, as well as laboratory and flight testing.
