Unique position must be kept among the three linear CCD cameras. Optical lens is one of pivotal parts  MTF  the ground resolution power is 5m  resolving power  the distortion is 3/10000. They meet the need of user. 2009 SPIE.  distortion are its important techno-items. The optical lens of space tridimensional mapping camera is the key to accomplish the tridimensional mapping mission. In order to meet the need of user  a design on optical lens of transmission semi-telecentric beam path in image space is expounded  and assembly method based on DFT(Design For Test) of single lens suit and whole optical lens are expounded. The test results indicates that the MTF of optical lens referred in the paper is 0.45(@77lp/mm)
