Abstract

Transmittance and reflectance measurements on wirecloth and electroformed metallic meshes are presented in the region 0.01 ≤ λ/d ≤ 5. The results were obtained under equal geometric optical conditions with a vacuum grating spectrometer. The measurements are used for the construction of a transmission bandpass filter in the wavenumber region ν > 18 cm−1. In order to be able to construct a bandpass filter in the entire far ir, a reciprocal grid is investigated and found to be suitable as a transmission low pass filter characterized only by geometrical parameters.
