Paper Abstract

In this paper, several collimator systems that may be used in the IR region with no central obscuration are discussed. One of them is a two-mirror asymmetrical system with the secondary of high order asymmetrical surface. The system has been realized in practice. Optical design shows that the image spot is diffraction limited at the center of field, and is about 1.8 arcsec at the margin of +/- 0.6 degree(s) field. Due to technological defect, the real image spot is about 1.8 arcsec at the center and 4.2 arcsec at the margin of field.
