Patent ID: 6894481

Claim:
A method of measuring output light intensity from laser chips mounted on respective carriers on a fixture, comprising the steps of: moving the fixture to in turn bring the chips to a measurement station; wherein, for each chip, moving the fixture to bring the chip in front of a TV camera connected to a vision system for determining x and y coordinates of objects viewed by the TV camera; determining the coordinates of the chip on the fixture by means of the vision system; moving the fixture in response to the coordinates of the chip on the fixture to bring the chip in front of a NIR camera connected to the vision system for determining x and y coordinates of objects viewed by the NIR camera; igniting the laser chip; determining the coordinates of a point of maximum light intensity from the chip by means of the vision system; and moving the fixture in response to the coordinates of the point of maximum light intensity to bring the chip to the measurement station to measure the light intensity.
