  • Patent number: 5255167
    Abstract: A finger mounted laser spotlight is constructed of a near-infrared continuous wave laser diode powered by a miniature power supply powered in turn by a nine volt battery. The laser diode is mounted inside a cylindrical heat sink housing which includes a focusable lens assembly. A momentary switch is connected in-between the power supply and battery. Cables interconnecting the components are sized to preselected lengths so that, when the power supply and battery are positioned over a wrist or other portion of the arm behind the fingers, the laser diode and housing are positioned over an index finger and the momentary switch is positioned between a thumb and index finger. In use, the momentary switch is pressed and held to provide a beam of near-infrared light.
