Application of automatic centering system in laser particle size analyzer

  Since the small-angle detector is only about 100 microns away from the center of the detector, the optical path system shifts or distorts due to mechanical vibration, thermal expansion and contraction, and desktop inequality, which can easily cause the main beam to deviate from the center of the detector and irradiate to small angle detectors, causing these detectors to saturate and unable to detect the scattered light signal produced by large particles, resulting in erroneous results.

  The function of the automatic centering system in the laser particle size analyzer is to ensure that the laser beam passes through the center point at any time, so that the detector can effectively receive scattered light from all angles, so as to ensure the accuracy and reliability of the measurement results, and ensure the resolution and measurement of the laser particle size analyzer. precision. Ensure that the laser particle size analyzer is in the best condition.
