Description

Technical Field

[0001] The present invention relates to the technical field of optical instruments, and in particular to a pentaprism optical path adjustment device adapted to a vertically mounted rotation axis. Background Art

[0002] The method for measuring the perpendicularity error between linear axes is relatively mature. It can be measured using a laser interferometer and an autocollimator, combined with an optical path conversion device such as a pentaprism. However, measuring the perpendicularity error between a rotational axis and a linear axis is relatively difficult, so it is necessary to accurately characterize the physical center of rotation of the rotational axis.

[0003] The operating principle of the traditional pentaprism optical path adjustment device is to change the direction of the optical path by mechanically rotating the pentaprism to achieve adjustment of the optical path. This device is based on the principle of reflection and refraction of light and is relatively simple to operate. However, the traditional design has the disadvantages of low adjustment accuracy, poor stability, and will be affected by external interference and affect the accuracy of the optical path. The pentaprism optical path adjustment device of the prior art has been optimized on the traditional basis and adopts a more advanced rotation mechanism and control structure to improve the convenience and repeatability of adjustment. However, in actual use, the above device has angle adjustment deviations. The main reason is that there is currently a lack of an adapter mechanism for vertically installing the rotating axis. The lack of this structure will make it impossible to ensure vertical alignment of the rotating axis during installation, thereby introducing errors in the angle adjustment process, causing the optical path to deviate from the expected direction. For this reason, a pentaprism optical path adjustment device adapted to the vertically installed rotating axis is proposed to solve the above problems. Summary of the Invention
