Paper Abstract

Aiming at the characteristics of the large format aerial measuring camera with larger field, lower distortion and telecentric beam path, a new optical system with field of 75° and lower distortion was designed in this paper. The optical system selects inverted telephoto as the initial structure instead of symmetric structure. The optical system is all sphere and has the advantages of compactness ,long back working distance and easy to fabrication and alignment. The result shows that the focal length is 135mm,with the relative aperture of 5.2 and the field of 75°,meanwhile , the modulation transfer function(MTF)is higher than 0.3 at the 100lp/mm,the distortion is lower than 0.01%,the biggest angle of incidence on image surface is smaller than 20°. This optical system can be used for the large format aerial measuring camera.
