Alignment and Calibration of Long-Focus Three-Mirror Lens with Eccentric Position of Image Field

The alignment of long-focus three-mirror lens with eccentric position of image field is considered. It is offered to use for this purpose the compensation method of checking the aspheric surface with the help of the spherical mirror (Maksutov's method). The interferometer scheme is also suggested that allows one to simultaneous observe in the image field the interference pictures from different mirror surfaces. Problems of focusing, check and photogrammetric calibration of optical and electronic apparatus based on the three-mirror lens with the eccentric image field are discussed.
