Abstract:
An apparatus for positioning a light beam modifier relative to a light beam source to optimize a beam characteristic at one or more desired locations along the path of a beam comprising:a light source for emitting a first light beam along a first beam path; a first light beam analyzer positioned at a first desired location along said first beam path for continuously measuring a characteristic of said first light beam emitted from said light source and generating a value signal based on said measurement; a first light beam modifier axially aligned along said first beam path between said light source and said first light beam analyzer, said first light beam modifier being movable along said first beam path relative to said light source; and a host computer electrically connected to said first light beam analyzer and said first light beam modifier, said host computer receiving said value signal and generating a focusing signal for axially adjusting said first light beam modifier along said beam path to provide an optimal beam characteristic at said first location.
