High precision optical components

Using both traditional and computer-controlled polishing (CCP) techniques, Bertin Winlight produces a wide range of optical components, including: Plano, spherical, on-axis/off-axis aspherical mirrors, lenses, prisms, cylindrical and toroidal mirrors, image slicers, freeform optics, etc., based on classical materials (Glass, ceramics, silica), aluminium, crystals and SiC (Silicon Carbide). To do so, the company masters the most advanced polishing techniques: Roughing, aspherical polishing (Freeform up to ø800 mm), MRF technologies (Magneto Rheological Finishing), IBF polishing (Ion Beam Figuring), Diamond Turning, etc. In compliance with the most demanding processes of the sector, Bertin Winlight is equipped with clean rooms (ISO 5 – ISO 6) to assemble, test and qualify its components and optical subsystems, therefore guaranteeing their in-flight performance in flight.
