Abstract
The uncertainty of optical transfer function (OTF) measurements of lens systems -- as one example of high-precision optical measurement technique -- can be greatly reduced by computer-aided measurement control and analysis. Improvements resulting in a high repeatability are described and the problems of some analysis concepts are discussed. With such a high repeatability (10-3) and resolution possible, the influences of temperature and the resulting thermal expansion dynamics of the mechanical set-up and the measuring system itself become factors limiting the reproducibility. Realizations of temperature controlled or thermally insensitive designs are presented.
