The AccuRange™ CCS Prima white light confocal displacement sensor is the most precise measurement system from Acuity. Using a novel optical principle of measuring the reflected light’s component wavelengths, these confocal sensors measure distance and position to within tens of nanometers. These compact probes can measure to opaque, shiny or even transparent surfaces.
Unlike the other Acuity distance sensors, the Prima Confocal systems are comprised of an optical measurement "pen" and a separate controller. This controller houses all of the electronics, light source, etc. Only emitted white light and reflected signals are passed between the pen and the controller via a thin fiber-optic transmission cable.
The Confocal-Chromatic Sensors (CCS) are offered in a variety of measurement ranges and standoff distances, each with corresponding resolutions. The shortest-range models resolve to 5 nanometers of height change! |
