Characteristics Of Automatic Centering System
An automatic centering system is installed in all of Bettersize laser particle size analyzers. The function of the automatic centering system is to ensure that the center point of the detector is always on the focal plane of the Fourier lens, while ensuring that the laser concentrated by the lens is always illuminated at this center point.
Dozens of photodetectors of the laser particle size analyzer are arranged outward from the center point. The detector near the center point is only a few tens of micrometers away. If the laser focus is lightly offset, it will be straight on the photoelectric detector near the center, leading to detector saturation and failure to detect properly. With the automatic centering system, the laser beam can be used to illuminate the concentrated laser beam to the center point, thus ensuring that the system is always in an optimal state.
