Paper Abstract

The optical properties of materials used in LWIR spectral filters are strongly temperature dependent. Spectral transmittance curves are presented for several interference filters and filter substrates at room temperature and at cryogenic temperatures. The dependence of out-of-band rejection upon optical geometry is also discussed.
