Abstract
We describe a low-pass filter that provides high in-band transmittance and excellent rejection at nu > 100 cm^-1. The transmittance of the filter components was measured at liquid-helium temperatures from 10 to 10,000 cm^-1. The total transmittance is > 50% for nu < 50 cm^-1 and is calculated to be < 10^-9 for nu > 300 cm^-1. The filter was successfully used in a liquid-helium-cooled, rocketborne, far-infrared absolute photometer.
