Abstract

Illumination unit for an apparatus, particularly for the implementation of diaphanoscopic examinations at a human, animal or botanical examination subject, has a monolithic semiconductor laser diode bar with driveable laser diodes that emit radiation as well as at least one optical arrangement for collimating and/or focusing the emitted laser radiation. The laser diode bar and the optical arrangement are mounted at a common carrier, and the laser diode bar is connected to pin-like terminal elements at the carrier for diode drive, that are in turn connected or connectable to terminals provided at a carrier plate accepting the carrier. A radiation-transparent covering that encapsulates the carrier.
