Optical design of the uncoaxial three-mirror system with wide field of view and long focal length

Guang Jin

Abstract

The characteristics of uncoaxial three-mirror system are high resolution, wide field of view, long focal length, light weight and small volume. It satisfies the requirement of remote sensing and space photography. The design principle of the uncoaxial three-mirror system is introduced. With the help of ZEMAX software, a uncoaxial three-mirror system is given. It has a focal length of 2 000 mm, F number of 9 and all surfaces are conicoid. It is shown that the system attains a field of view 7°×3° and MTF is higher than 0.5 at 50 lp/mm.
