ABSTRACT:
A microlens for a multiple emitter laser diode consists of narrow slices cut out from molded aspheric lenses. Each slice is mounted in front of one emitter and the slice position is adjusted in the cross-emitter direction to have all emitter images aligned in a straight line, thus compensating for any lack of straightness in the multiple emitter diode.
