  • Optical switch for dental/medical light guide
    Patent number: 6079861
    Abstract: A system for supplying optical power uses an optical switch or shutter at the handpiece. The optical switch is positioned between an open light-transmitting position and a closed light-reflecting position. A detector at the base of the system can be used to detect the position of the optical shutter in some situations. This can be used to control the operation of a high-intensity light source. In this manner, the system can be controlled at the handpiece without using electrical power at the handpiece.
