Problems solved by technology

Because the optical path adjustment requires lighting conditions, the beam emitted by the autocollimator is generally not visible in the illuminated environment, so it is difficult to adjust the relative position and direction of the autocollimator and the mirror in the above cases

Abstract

The invention discloses an auxiliary collimation device of an autocollimator, and belongs to the technical field of optical detection. When auto-collimation testing is carried out, the optical axis of the autocollimator needs to be collimated with a light reflector, and meanwhile the normal of a light reflector face is parallel to the optical axis of an objective lens of the autocollimator. If the distance between the autocollimator and the light reflector is large, time and labor are wasted when the light path is adjusted, and therefore the measuring efficiency and the measuring accuracy are reduced. According to the auxiliary collimation device of the autocollimator, the relative positions and the relative directions of the autocollimator and the light reflector can be coarsely adjusted, the position of a center light beam of the autocollimator is indicated through a visible laser beam, and the position and direction relation between the autocollimator and the light reflector is judged by observing the position of a laser spot on the light reflector and the position of the reflected laser spot. On the premise that the autocollimator and the light reflector are already accurately collimated, matched calibration of the auxiliary collimation device of the autocollimator and the end face of a lens cone of the autocollimator can be further achieved.

Description

technical field [0001] An autocollimator auxiliary alignment device is an optical path adjustment auxiliary device during autocollimation measurement, which is used for preliminary adjustment of the position and direction relationship between an autocollimator and a mirror, and belongs to the technical field of optical detection. Background technique [0002] Autocollimator is a commonly used measurement and testing instrument for small angle measurement by using the principle of optical self-collimation. It has unique advantages in realizing multi-dimensional and non-contact measurement of small angles, and is widely used in angle detection of optical components, platform flatness detection, mechanical shaft shake detection, precision guide rail straightness detection, and small deformation of mechanical structures. In precision measurement such as detection. [0003] During autocollimation measurement, the beam emitted by the autocollimator must enter the field of view of...
