  • Patent number: 6518996
    Abstract: A yoke is supported on a frame for vertical movement in a Z direction above a transparent work support that is mounted on the frame for horizontal adjustment in a Y direction, normal to the Z direction. A carriage which is mounted for horizontal adjustment on the yoke in an X direction, normal to the Y and Z directions, carries a video camera and lens system which overlies the work support to project an image of an inspected workpiece to the camera. A substage collimator which is mounted on the frame beneath the work support for adjustment in the X direction, has thereon a souce of collimated light that registers with the lens system. The collimator is connected to the carriage to be moved in unison therewith in the X direction, and always to maintain the light source in registry with the lens system.

  • Patent number: 5690417
    Abstract: A plurality of light emitting diodes are secured coaxially around the lower end of a cylindrical objective lens housing in radially spaced, circular arrays or rings disposed coaxially of the housing. The diodes in each ring are equi-angularly spaced from each other about the axis of the housing; and their light emitting ends overlie a work table so as to direct beams of light obliquely downwardly onto an object supported thereon. The diodes are energizable in generally pie-shaped sectors disposed coaxially of the housing so that arcuate clusters of diodes in a given segment may be illuminated to enable the orientation of the resultant illumination to be varied. The diodes of each ring may have their beam axes inclined at different angles to the axis of the housing so that the inclination of the projected illumination may be varied by selected energization of the rings; and a collimating lens may be secured over the light emitting end of each diode.
