Abstract

This paper describes a narrow bandpass filter which is temperature controlled to maintain optical characteristics while operating in an ambient temperature range of −20°C to +70°C. Pertinent sources of bandpass shift and means for their control are discussed. The analytical approach, resultant filter assembly configuration, and performance test results of the assembly are presented.
