Embodiment Construction
[0010] The present invention is divided into the upper rotating part and the lower fixed part. image 3 Including: theodolite azimuth axis 1, the first connecting frame 2, the first optical collimator pigtail 3, the first optical collimator shell 4, the first optical collimator lens group 5, the second optical collimator A lens group 6 , a second optical collimator shell 7 , a second optical collimator pigtail 8 , a second connecting frame 9 , and a theodolite base 10 .
[0011] The first connecting frame 2 and the second connecting frame 9 are made of firm and less deformed metal material, the inner wall of the first connecting frame 2 is processed black, and their inner walls are rougher to prevent the surface of the light collimator lens from collimating The reflected light enters the optical collimator after being reflected by the inner wall of the first connecting frame 2, causing interference. In order to better absorb the reflected light, an absorbent carbon black is ad...
