Abstract

A near diffraction limited catadioptric lens of EFL=324.4 mm and f/3.6 was designed for the spectral range 546 to 852 nm. This is a 5 element lens with a field of view of ±2.5°. The obscuration ratio is 0.5 and relative illumination at the edge of the field is 81.4%. The distortion is less than 0.16%. This lens can be used for high resolution imaging applications using CCDs. The design details were presented in this paper.
