Annotation	Two measuring techniques are presented in this paper. These techniques are able to measure and process the shape of the reflecting surfaces. In the first part of the paper the theory and modifications of the optical, mechanical and software design for the Hartmann wavefront analyzer are described. This new method is applied to the non-contact measurement of concave-mirrors shape and objectively defines the shape and specifies the difference of the segment shape from an ideal surface with micrometer accuracy. This difference determines essentially the mirrors image quality. In the second part of the paper attention is concentrated on the other main factor that affects image quality— surface roughness. Thereinafter, physical background and usage of the measuring system and results are presented.
