The precision of light: the benefits of non-contact chromatic confocal measurement - the-precision-of-light-the-benefits-of-non-contact-chromatic-confocal-measurement
Chromatic confocal technology exploits the principle that through appropriate optical design techniques, white light is broken down into its constituent wavelengths: colors from blue to red that, when properly sized, produce a range of sensors and controllers with excellent metrological performances.
Marposs offers accurate solutions down to the nanometer level for measuring distance, roughness, profiles, 3D reconstructions, and image analysis for defect control. Confocal probes could also be implemented to measure the thickness of single and multilayer transparent materials such as glass and plastic.
