  • Gemstone marking system with a focus sensing unit for sensing relative disposition between a marking surface of the gemstone and a focal plane of a laser beam
    Patent number: 6649863
    Abstract: A gemstone marking system includes a focus sensing unit sensing relative disposition between the marking surface of the gemstone and the focal plane of the laser beam. The focus sensing unit includes a light source emitting a collimated optical beam directed in parallel to the focal plane of the laser beam and overlapping regions positioned in close proximity to the focal plane of the laser beam, an optical detector measuring the power of the sensing optical beam (the power of the sensing optical beam depends on a relative disposition between the marking surface of the gemstone and the focal plane of the laser beam), and a signal processing unit operationally coupled to the output of the optical detector for receiving and processing data corresponding to the relative disposition of the marking surface of the gemstone and the focal plane of the laser beam. The signal processing unit, in response to the data obtained from the optical detector, automatically controls the position of the gemstone.
