Abstract

The use of the Hartmann interferometric optical testing method is described. The method is applied for laboratory testing during mirror manufacturing. Possibilities and advantages of the method in testing mirrors of the 8 m class are discussed. A telescope wavefront sensor based on the method is described and test results of the 2.5 m Nordic Optical Telescope are presented.
