Auto centering function

Guarantee the perfect condition of optical system

The diameter of laser detector center point is only 100 microns. When processing the analysis, the laser detector center point must coincide with the focus point of the back lens; otherwise, measuring error will occur. The auto centering function of Bettersize particle size analyzer alleviate the alignment problem altogether. Automatically moves the laser detector center point to the focus point of the back lens before each test, centering function guarantees the perfect condition of the optical system; therefore, provides accurate and repeatable testing results.
