[0002] A laser particle size analyzer is an instrument for measuring and analyzing the abundance of physical particles. Based on the dispersion system, it is divided into wet testing instruments, dry testing instruments, and combined wet and dry testing instruments. Its principle is that when light propagates, the wavefront is restricted by pores or particles of a scale equivalent to the wavelength. The emission of each element wave at the restricted wavefront as the source interferes in space, resulting in diffraction and scattering. The spatial (angular) distribution of diffracted and scattered light energy is related to the wavelength of the light wave and the scale of the pores or particles. The sample window is an important component of the laser particle size analyzer.
[0003] However, the current method of connecting the sample window to the laser particle size analyzer is quite cumbersome, which means that it takes a lot of time and causes a lot of trouble when the sample window needs to be disassembled for cleaning.
[0004] In view of this, the present invention proposes a laser particle size analyzer sample window that is easy to disassemble and clean. Utility Model Content
