1、 Laser displacement sensor

Using the triangle measurement method, a laser beam is emitted onto the surface of the polarizer, and the position of the polarizer can be measured by detecting the reflection position.

2、 Thickness measurement principle

The thickness measurement module is composed of two laser displacement sensors that are aligned vertically. The two sensors measure the position of the upper surface of the measured object and the table below

The position of the face,Calculate the thickness of the tested object.The advantage of laser thickness gauge is that it adopts non-contact measurement, which is more convenient than contact thickness gauge

Accurate, not affected by wear and tearAnd the loss of accuracy.As shown in the figure below, the thickness of the polarizer is C=L-A-B.
