Spectral confocal displacement sensor is a new type of ultra-precision measurement sensor, which has been developed for decades in foreign countries, and has been issued in recent years in China. With the continuous maturity of technology, the stability of spectral confocal displacement sensor has been further improved, thus realizing the application of various detection scenarios. Compared with traditional laser displacement sensor, What are the advantages of spectral confocal? Today, Li Yi technology Xiaobian will introduce it to you, and let's understand it:

Compared with traditional laser triangulation, spectral confocal is to use a special lens to amplify the color and light color difference, obtain distance information by reflecting light waves, and detect the internal components of the lens will not be affected by light intensity, and will not generate heat, and have high stability and accuracy.

Secondly, it perfectly solves the problem of misalignment of measuring point and deviation of measuring Angle of traditional laser displacement sensor. When we use the traditional laser displacement sensor, the measurement position or spot size will change with the measurement height, and the spectral confocal principle uses coaxial confocal, which can ensure that even if the measured object is tilted or warped, it can also be measured with high precision, and the measurement point will not change. And there is no aberration interference, so the measurement accuracy will not be affected.

Finally, not troubled by the material, when the traditional laser measures the transparent and translucent material, the light spot often takes perspective or forms light and shadow on the surface, affecting the measurement, and the spectral confocal displacement sensor can perform high-precision measurement without strict Angle adjustment.

The above is the introduction of the advantages of Liyi Technology in spectral confocal displacement sensor. If you need to know more, welcome to pay attention to Liyi Technology.
