The core research and development staff of Polygraph Technology have more than ten years of experience in the field of laser displacement measurement and 3D scanning, and found that spectral confocal is more accurate and adaptable than laser.

Glue by its own surface tension after the surface of the curved mirror, even with the most advanced laser displacement sensor measurement, because the mirror tilt will reflect the laser away from the direction of the receiving lens, many materials simply can not produce the correct result, and installed after the dispersion confocal lens of the glue top perfect arc curve can be shown. In particular, the measurement of transparent or translucent glue is more difficult, and it is easy to measure the height of glue with a spectral confocal probe.

A German company producing dispensing devices, in order to measure the height of its dispensing difficulties, the final use of spectrometer technology spectral confocal sensor equipment finally perfect solution to the problem of glue height measurement, and has been used in good condition.

The printing of silver paste on ceramic is a basic process for the production of many electronic components. Because of the light transmittance of ceramics, the use of laser measurement is easy to produce deviations. Finally, the spectral confocal principle and magnetic suspension automatic XY precision motion platform are adopted to solve the problem of measuring the thickness of silver paste.

According to the measurement principle of spectral confocal, the controller needs to analyze the reflected spectral signal. However, the sensor in the controller can still detect some signals without measuring the sample. These signals, often referred to as dark signals, consist of stray light reflected back from the fiber coupler and measuring head.
