ABSTRACT:
An illumination system (12) for an optical inspection and sorting apparatus (10) includes a rare gas discharge lamp (36) for emitting select wavelengths of radiation. Rare gas discharge lamp (36) includes a light transmissive outer envelope (58) and contains one or more rare gases, and in particular neon, argon, or xenon. A hemi-elliptical reflector (48) having reflecting surface (38) directs the select wavelengths of radiation toward target specimens (16) in optical scanning area (24) in illumination area (20).
