SCHOTT has been developing fiber-optical products for more than thirty years and they can be found in the most varied of applications. The benefits of these products speak for themselves: fiber optic light guides are extremely versatile components that can be flexibly adapted to the most widely varying requirements regarding design, installation and environment. Extremely flexible glass fiber cables with diameters from one to seven millimeters transport light to the required point. For this purpose the light from a lamp with a reflector is projected onto the glass fibers which transport it elsewhere. An end feroule specific to the particular application is fitted to the end of the glass fiber light guide to provide the desired effect from the safety point of view. Transmitting the actual light instead of electricity is a powerful argument in favor of this technique, as is the fact that glass does not catch fire.
