Measuring glass thickness: It can detect the surface of glass and also measure the thickness of glass.

Digital subpixel processing adopts digital subpixel processing technology: one pixel can be subdivided into 65536 subpixels (256 × 256), making its linear accuracy more than twice that of traditional displacement sensors.

High precision sensitivity correction: The high-resolution electronic shutter speed is 1/485 of the sampling period, which helps to ensure a stable peak state of light reception, automatically optimizing the light reception, and maintaining stable detection even on unstable surfaces.
