Abstract
The essential features of apparatus suitable for routine mapping of pairs of wedged uncoated optical flats are described. In this method the aperture of the pair of flats is scanned in a regular pattern, and information about the spacing uniformity is derived from the interference of light reflected from the flat surfaces. Accuracies within about lambda/500 are obtained.Keywords
