The spectral confocal displacement sensor adopts the principle of dispersion confocal, and the surface of mirror, transparent and translucent objects can also have super-strong angular characteristics. Spectral confocal displacement sensors are widely used in non-contact measurement of displacement, vibration, deformation and thickness of transparent objects with high precision. The following vertical instrument for you to talk about dispersion confocal is what?

The principle of spectral confocal displacement sensor is to use wavelength information to measure distance. The light source emits a broad spectrum of polychromatic light (white), which is spectrographically dispersed through a dispersive lens to form monochromatic light of different wavelengths. The focus of each wavelength corresponds to a distance value. The measured light is reflected from the surface of the object, and only the monochromatic light that meets the confocal condition can be detected by the spectrometer through a small hole. The range value is obtained by calculating the wavelength and zoom ratio of the sensed focus.

The coaxial confocal principle of spectral confocal method can ensure that even if the object to be measured is tilted or warped, it can be measured with high precision, and the measurement point will not change. The spectral confocal displacement sensor has strong angular characteristics, and the maximum observable inclination can reach 87 degrees.

Spectral confocal displacement sensor does not have aberration interference because of its dispersion confocal principle. Even if the Angle of the measured object is too large, it will not affect the measurement accuracy. It can also have superior angular properties on the surface of mirrors, transparent and translucent objects. With spectral confocal displacement sensors, precise measurements can be made without strict Angle adjustment. Even if the measured object jumps during the movement, it will not affect the measurement too much.
