Abstract
Method and apparatus for scribing indicia into a surface using a laser as an emission source. Means are provided for controlling the beam scan over the surface being inscribed responsive to a digitized control signal representing the indicia. Laser power is controlled to avoid damaging the structural integrity of the glass. The system is suited for automation both for the input of data representing indicia and for the actual inscribing operation. The apparatus includes an emitter housing containing a laser and marking head for positioning the beam on the surface. The emitter housing further includes means for controllably directing the output beam to form the desired pattern in the surface and locating pins which cooperate with system circuitry to permit laser operation only when the emitter housing is properly located with respect to a surface being etched. A support system which includes a controller is provided which comprises means for data input and conversion of the input data into a control signal for controlling the laser.
