What is Chromatic Confocal Sensor
Chromatic confocal sensor, also called confocal displacement sensor or confocal distance sensor, is a high precision measuring instrument/device. It is widely used to measure displacement, distance, thickness, height, depth, flatness, roughness, profile, radius, porosity, vibration of the objects. It disperses white light to a number of chromatic lights and figures out the displacement data by analyzing the wavelengths of the reflecting chromatic lights.
A beam of white light will be dispersed to different chromatic lights after passing through a hole and a lens. Each light will focus on different position on the optical axis. All lights irradiated on the the surface of the object will reflect back.
All reflecting lights will reach a spectroscopic component. The lights which are not irradiated on the intersection point of the optical axis and the surface of the object will be led to the periphery of the hole of the spectrum analyzer.
Only the light irradiated on the intersection point of the optical axis and the surface of the object can enter the the spectrum analyzer. The displacement from the sensor to the object will be figured out through analyzing the wavelength.
