Abstract

The High Altitude Observatory (HALO) is an instrumented gulfstream IIb aircraft sponsored by the US Army Space and Strategic Defense Command as an optical data collection platform. Capable of operation at altitudes above 50,000 feet, the HALO's highly diverse and flexible sensor suite has provided infrared, visible and ultraviolet data on numerous BMDO, DOD, and NASA test programs. This paper describes the design, fabrication, and testing of two large zinc selenide infrared windows employed by the aircraft's primary sensor system, the Infrared Instrumentation System. The paper describes the design, fabrication, and testing of the windows and coatings, the window proof testing for flight qualification, and summarizes the current operational experience with the windows.
