Chromatic White Light Sensor
Solarius has introduced a new line of chromatic probes based on white light confocal technology. The use of chromatic "splitting" allows for sub-division of the white light spectrum to correspond to unique Z-axis displacement levels. Each wavelength will be perfectly focused at a different Z height using the confocal principle, all out of focus light is rejected resulting in only the in-focus point been registered.
The use of monochromatic wavelengths to discern Z height eliminates the need for moving components in the sensor resulting in a robust extremely accurate solution.
