Abstract
An apparatus and method for semi-automatic focusing and assembling of a light beam modifier, such as a lens, relative to a light beam source to optimize the light beam characteristics at one or more locations along the beam path using one or more light beam analyzers ( ). A host computer compares the measurements and axially adjusts the light beam modifier. The apparatus may include two focusing stations ( ) for alternately focusing and assembling two light source assemblies, two beam splitters ( ) for splitting the light beam emitted from either focusing station into three components, and three light beam analyzers for measuring the beam characteristics at three locations. The apparatus may also include a video camera for automated or manual pointing of the laser beam, a semi-automatic glue dispensing system for fixing the light beam modifier relative to the light source and an automatic laser power-up circuit.
