    摘要: An apparatus for measuring output light intensity from laser chips mounted on respective carriers on a fixture, comprises a control unit for moving the fixture to in turn bring the chips to a measurement station, and a TV camera and a NIR camera both connected to a vision system for determining x and y coordinates of objects viewed by the TV camera and the NIR camera, respectively. The control unit is adapted to move the fixture to bring the respective chip in front of the TV camera to determine the coordinates of the chip on the fixture, move the fixture in response to the coordinates of the chip on the fixture to bring the chip in front of the NIR camera to determine the coordinates of a point of maximum light intensity from the ignited chip, and move the fixture in response to the coordinates of the point of maximum light intensity to bring the chip to the measurement station.
