Abstract

The Astronomy Instrumentation Group at Cardiff University has been developing metal mesh optical filters for more than 30 years. They are currently in use in ground-, balloon- and space-based astronomical instruments and in many laboratory-based THz applications. Here we briefly illustrate the current state of the art with respect to these quasi-optical components (low-pass, high-pass and band-pass filters, dichroics and beam-dividers).
