What is the principle of spectral confocal displacement sensor? Shenzhen Liyi Technology gives you a brief introduction:

A beam of white light (or a mixture of multi-wavelength light) passes through a small hole, through the lens to focus the different wavelengths on the optical axis, dispersively forming a rainbow distribution band, shining on the sample, and some of the reflected light on the surface is reflected back.

The light that is not illuminated at the intersection of the optical axis and the surface of the object passes through the splitter component, and the light illuminated around the other small hole is blocked, and cannot be illuminated to the spectral analyzer, and will not interfere with the measurement.

The light shining at the intersection of the optical axis and the surface of the object passes through the splitter component and illuminates the spectral analyzer through the small hole. According to the wavelength calculation, the distance between the lens and the measured object can be obtained.
