Go!Foton brings to market the SELFOC Rod Lens product produced by NSG Group in Japan. The origin of its SELFOC lens dates back to 1968 and the original objective was to develop a lens for fiber-optic gastric endoscope. In the process, the NSG researchers succeeded in producing the world’s first gradient index lens in a glass rod. From there, they developed lenses that could transmit images and light coming from one end of the glass even when both ends were flat. The product name SELFOC comes from “self-focusing.” In this lens, the index of refraction declines rapidly as light moves from the center to the periphery. Today the SELFOC Rod Lens is widely adapted in endoscopy applications.
