Light Guides

The light guide cone/light guide block/light guide strip is processed by fine grinding, grinding, measurement, ultra-high precision polishing, coating and other processes. Under the condition of precise control of the machine tool and the processing environment, the ultra-high precision correction polishing technology is used to polish the window surface, and the optical guide cone/light guide block is achieved with the optical plane shape accuracy ≤0.1 micron and the surface roughness Ra≤0.01 micron. It is a key component in cosmetic laser or intense pulsed light applications.
