Bertin Winlight makes high value-added optical components, ranging in size from just a few millimeters to 1.5 meters. Our temperature-controlled optics production plant spans some 2,200 square meters and is located in Pertuis, in the Vaucluse region of southeast France. We deploy both traditional and computer-controlled polishing (CCP) techniques, using both deterministic manufacturing methods (computer numerical control, or CNC) and traditional methods such as hand polishing to turn out high-quality components with minimal surface roughness down to 0.1 nm RMS.
