The PSM (Point Source Microscope) adjustment microscope originated from the Optical Center of the University of Arizona, USA. It is a universal auxiliary adjustment tool, mainly used in the adjustment of complex optical systems. It can effectively help determine the center position of each surface of the optical element, thereby completing the alignment of the optical system and the optical axis.

principle
During the optical system adjustment process, if the focus of the PSM objective lens is precisely positioned at the center of the curvature of the spherical mirror, the reflected light will be focused into a reduced point at the center of the detector. Otherwise, the reflected light will not be focused or form a centrally symmetrical image. At this point, the PSM software can be used to obtain the spot size and deviation distance formed by the reflected light, providing guidance for further adjustments.

Applications
- Used to study small samples or large targets.
- Can be used as a star point method to detect imaging systems on a CMM or x-y-z stage; the energy percentage data is distributed in a circular area, and the aberration can be seen to gradually decrease during the off-axis mirror calibration process.
- Use the autocollimation method without an objective lens.
- With the help of a CMM or a simple adjustment fixture, complex optical systems can be quickly adjusted.
- Quickly check the adjustment and positioning of optical systems.
- For the measured parts on the optical platform or guide rails, the curvature radius of the surface can be measured.
- Calibration and positioning of optical surfaces and mechanical reference surfaces, such as positioning balls, bore gauges, etc.
