The role of three-dimensional automatic optical path alignment system in laser particle size analyzer

May. 07, 2022

The three-dimensional automatic optical path alignment system is an application of a patented technology created by Winner Particle Instrument Co., Ltd. in the laser particle size analyzer. Why is the optical path alignment required?

 

Since the small-angle detector is only about 100 microns from the center of the detector, it is easy to cause the main beam to shift or twist due to mechanical vibration, thermal expansion and contraction, uneven tabletop, or vibration during international transportation. Deviating from the center point of the detector and irradiating the detector with a small angle will cause these detectors to fail due to saturation, unable to detect the scattered light signal generated by large particles, resulting in erroneous results, so optical path alignment must be performed before testing. The function of the three-dimensional automatic centering system in the laser particle size analyzer is to ensure that the center point of the detector and the focal point of the optical path lens are coincident at any time, so that the detector can effectively receive scattered light from all angles, ensure the accurate and reliable test results, and ensure Resolution and measurement accuracy of laser particle size analyzers.
