Measure the wall thickness of the glass tube

First, fix the glass tube on the measuring table and take the highest point of the 3 vertical objects (as shown in the figure above).

This time, the H4UC full range controller is used with D40A19. The D40A19 has longer length and better Angle performance, which is very suitable for measuring side items.

Through the spectrometer spectral confocal measurement, the value is 8418.487μm, more high-precision measurement needs, welcome to pay attention to spectrometer technology.
