In the spectral confocal displacement sensor system, the measuring range of the system is affected by four factors: 1) the spectral distribution range of the light source

Spectral confocal displacement sensor is a device that establishes the corresponding relationship between distance and wavelength through the principle of optical dispersion, and uses the spectrometer to decode spectral information to obtain position information. The light emitted by the white LED light source can be approximately regarded as a point light source after passing through the fiber coupler, and spectral dispersion occurs after collimation and focusing through the dispersive objective lens. A continuous monochromatic light focus is formed on the optical axis, and each monochromatic light focus has a different distance from the measured object.

With the continuous upgrading of 3C product appearance design and material technology, the technology of automatic measurement using spectral confocal displacement sensor has been more and more widely used in the processing and manufacturing process of 3C products in recent years. The Chinese automated measurement market defines the spectral confocal displacement sensor as a new type of sensor that can solve many difficult measurement applications with high accuracy.

With the continuous improvement of the level of automation technology in our country, the use of sensors is increasing, and the development and design of high-tech displacement sensor products have broad market prospects.

In recent years, with the continuous upgrading of 3C product appearance design and material process, the automatic measurement of 3C product processing and manufacturing process is increasingly using spectral confocal displacement sensors.

The color laser displacement sensor is one of the displacement sensors, which is suitable for long-distance detection, and gradually replaces the pull wire displacement sensor, which is used in industrial automation, transportation, steel, construction, wharf and other applications that need automatic distance displacement measurement and position control.
