Spectral confocal displacement sensor principle: a beam of white light (or multi-wavelength mixed light) through a small hole, through the lens will focus different wavelengths to the optical axis, dispersively form a rainbow distribution band, only irradiation in the optical axis and the object surface intersection
The light passes through the splitter component and shines through the aperture to the spectral analyzer, and the wavelength can be decoded to obtain the distance from the lens to the measured object
Advantages of spectral confocal displacement sensor
1, high resolution, independent intellectual property rights, not subject to foreign export control resolution restrictions, vertical instrument master core technology, according to the actual application needs of customers, flexible modification and adjustment design.
2, the measurement Angle is large, φ82mm lens to achieve the design Angle of mirror ±60°, non-mirror surface ±88°; Both set world records.
3, the background interference is small, the patented separation channel fiber, to solve the problem that has plagued the industry for decades, more than 50% less than the traditional fiber interference.
4, high light intensity, patented prism spectrometer products, linearity improved by more than 200%, light energy utilization improved by more than 200%.
5, the specifications cover a wide range, has covered 0.1~25mm range, from the range of 0.05~50mm can be customized. Minimum diameter 3.8mm.
6, good stability and high reliability: optical part: measuring lens lens all glue fixed death, good shock resistance.
Mechanical part: The controller comes with a shock-absorbing structure, the core module is flexibly suspended in the air, reducing external vibration, good temperature stability and small drift.
Optical fiber part: The connector is designed to prevent stupidity. When the connector is not aligned with the slot, the thread will not be locked to prevent measurement errors caused by not being inserted in place.
Line spectral confocal displacement sensorPrinciple: The original point spectral confocal point light source is extended to line light source. And through high-speed data processing, a series of data is formed by sampling several point signals on the feedback line spectrum signal, and the high-precision scanning contour of the measured object can be obtained by point cloud processing and the high-precision height data of each position ...
