本文叙述了远红外（100-800 μ）透射干涉滤光片的测量。这些滤波器的反射层是金属网。测得的精细度系数，10至60，是可比的值，可以获得在其他光谱区域的干涉滤光片。峰值透射值达到0.9。从这些测量的吸收率的单栅极已被确定。对可变间距干涉滤光片的测量表明，精细度与波长的平方成正比，这与用一维线栅反射层构造的干涉滤光片的理论预测一致。
This paper describes measurements on transmission interference filters for the far infrared (100–800 μ region). The reflection layers of these filters are metallic mesh. The measured coefficients of finesse, ten to sixty, are comparable with the values which can be obtained for interference filters in other spectral regions. Peak-transmission values up to 0.9 were reached. From these measurements the absorptivity of the single grids has been determined. Measurements on a variable spacing interference filter showed that the finesse is proportional to the square of the wavelength in accordance with theoretical predictions for interference filters constructed with reflection layers of one-dimensional wire gratings.
