Abstract

The reasons why thermal imaging lenses often fail to achieve their design performance specifications are discussed. Examples of lenses having centering errors and figuring errors are shown. The effects of using material with refractive index inhomogeneities are described. Methods for reducing the discrepancies between the design and actual performances in thermal imaging lenses are briefly outlined.
