According to the fact that the triaxial parallelism parameters of optical collimator effect in the its perfor-mance, a system used for testing triaxial parallelism of optical collimator is developed in this paper, which includes some key technologies such as parabolic off-axis lens, two spectroscopic and high precision CCD camera. The triaxial are optical sights white & infrared targeting axis, the laser launching axis. Via analyzing the optical path, the mathe-matical model of triaxial parallelism are built,and the error factors are analyzed and calculated. The system is calibrat-ed by autocollimation theodolite whose accuracy is 0.5″ and the experimental results show that the measurement error is<3″.
