Embodiment Construction

[0032] Such as figure 1 , the method of transferring the optical axis level reference of the present invention to the optical axis of the instrument, the optical axis level reference should be arranged on the vibration isolation foundation, and the specific steps are as follows:

[0033] 1) if figure 1 , arrange the long blister unit on the table of the vertical shaft, rotate the vertical shaft, observe the long blister unit, and adjust the feet of the vertical shaft at the same time to make the blister of the long blister unit horizontal, indicating that the vertical shaft is vertical Horizontal plane, when actually adjusting, multiple long blister units can be set on the entire table of the vertical shaft system;

[0034] 2) Install the flat crystal on both ends of the horizontal axis system through the azimuth and pitch adjustment tooling, rotate the horizontal axis system, use the autocollimator to monitor the flat crystal, adjust the azimuth and pitch adjustment tooling,...

Abstract

The invention discloses an optical axis horizon reference and a method for establishing the optical axis horizon reference. The optical axis horizon reference comprises a vertical shaft system, a horizontal shaft system, optical flats and a pitching adjusting tool. The vertical shaft system comprises a table. The horizontal shaft system is arranged on the table. The optical flats are arranged on two ends of the horizontal shaft system through the pitching adjusting tool. Monitoring surfaces of the optical flats are perpendicular to the horizontal shaft system. According to the invention, the transmission precision is high, the horizon precision of an adjusted optical axis is at the level of seconds of arc, and the repeating precision is high.

Description

technical field [0001] The invention relates to an optical axis horizontal reference and a method for establishing the optical axis horizontal reference. Background technique [0002] In optical instruments (collimator, autocollimator, telescope, etc.) It will greatly improve the efficiency of the test system, and also help to improve the overall accuracy of the measurement. The parent source of the horizontal reference is the horizontal plane, and the horizontal reference with a certain accuracy can be stably obtained by using water bubbles. The longer the length of the water bubble, the higher the accuracy, but How to transfer the horizontal reference to the optical axis of the optical instrument is another problem. Contents of the invention [0003] In order to solve the problem of establishing the optical axis level reference of optical instruments such as collimators, the present invention provides an optical axis level reference and a method for establishing the opt...
