Abstract
The problem of defining and isolating a wavelength band in the far infrared and submillimetre region (45 to 1000 μ) is particularly difficult because of the large thermal energy at shorter wavelengths that must be rejected. Metallic grid filters have been extensively studied during the past several years and are particularly suitable for high-sensitivity instruments because they function well in liquid helium. For use as filters in our balloon-borne experiments we have been studying the transmission and reflection characteristics of three types of metallic grids in the sub-millimetre wavelength region. While our results are not yet complete, they have enabled us to construct long-wave pass filters suitable for our experiments.
