Optical single-point sensor using chromatic aberration confocal method
Embedded optical sensor for high-precision and high-speed measurement of thickness and shape.
This is a single-point sensor using a chromatic aberration confocal method from Pretech, characterized by high precision and high-speed measurement. It has a proven track record in reducing measurement time for thickness and shape, as well as in full inspection. Due to the chromatic aberration confocal method, it is also possible to use probes with a large angular tolerance. There is also a budget sensor lineup available, starting from approximately 800,000 yen. *For more details, please refer to the materials. Feel free to contact us as well.*
