The CCS Prima White Light Confocal Displacement Sensor is the most precise measurement system from Acuity. Using white light LED, the system employs a unique measuring principle that separates emitted light into different colours and then uses a detector to identify the reflected colour signal.

Using a novel optical principle of measuring the reflected light’s component wavelengths, these confocal displacement sensors measure distance and position to within tens of nanometres. These compact probes can measure to opaque, shiny or even transparent surfaces. The systems are comprised of an optical measurement “pen” and a separate controller. This controller houses all the electronics, light source, etc. Only emitted white light and reflected signals are passed between the pen and the controller via a thin fibre-optic transmission cable.
