ABSTRACT:
Electro-optical device characterized by having been formed into an individual unit with an integral lens, and method to form the device. A lens, for instance a length of cylindrical microlens, is aligned with a diode strip having a plurality of diodes, for instance laser diodes, and attached to the lens. Subsequent to this attachment, the composite structure consisting of the diode strip having attached to it the lens is sectioned into individual diodes, each of which has a integral lens attached thereto.
