PSM Applications
Using The Point Source Microscope (PSM) To Find Conjugates Of Parabolic And Elliptical Off-axis Mirrors
ABSTRACT Although the PSM is primarily an alignment instrument, it can also be used to determine the conjugates of parabolic and elliptical off-axis mirrors. By positioning the PSM at the sagittal and tangential foci of the mirrors, the conjugate distances of the mirror can be found using a laser range finder, for example. Knowing the […]
Method Of Alignment Using A Laser Tracker System
1. Introduction: Laser trackers are an accurate and efficient tool for finding the locations of features in a threedimensional space but they rely on Spherically Mounted Retroreflectors (SMR) to return the laser beam to the tracker. If the feature cannot be contacted or it is not convenient to use an SMR another method must be […]
Centering with the PSM
Centering with the Point Source Microscope (PSM) is a perfect application. Centering with the Point Source Microscope (PSM) is a perfect application. When a spot of light from the objective focus is reflected back from a concave surface sitting on a rotary table, it will sweep out a circle on the video screen as the […]
