Abstract

Instruments for measuring the full aperture transmittance of thermal imaging lenses operating in the 8 to 14 micrometre spectral region are described, and examples of typical results obtained shown. The causes of discrepancies between the actual transmittances measured and those predicted from a combination of the anti-reflection coating performances expected and the material transmittances are discussed.
