Abstract

Low pass far infrared radiation filters with cutoff frequencies in the spectral region of 10–25 cm⁻¹ were required for a rocket-borne radiometer experiment. The paper describes the theory, fabrication, and laboratory transmission measurements of prototype grid filters investigated in a study prior to the construction of flight filters. Characteristics of the final flight filters are also presented.
