Paper Abstract

The effects of reducing the transmittance and MTF of the optics in a thermal imager on the subjective performance have been shown, as has an instrument for measuring the full aperture transmittance spectra of IR lenses. MTF degradations for large (ca. 2510mm diameter) monocrystalline germanium blanks have been described.
