Abstract
An illumination system for wire bonding at wire bonding locations which includes an illuminator having a highly light transmissive portion with an end surface and an axial bore extending therethrough and terminating at the end surface. The illuminator includes a first light source for directing light substantially axially through the bore to the end surface and a second light source for directing light substantially axially through the highly light transmissive portion to the end surface. The end surface is preferably a light diffusing surface. The bore is preferably tapered with the taper widening in a direction toward the end surface. The surface of the bore is preferably a light diffusing surface. The bore can alternately include a layer of highly light reflecting material disposed on its surface. The highly light transmissive portion has an outer surface which can include a layer of highly light reflecting material disposed thereon. The system further includes a mirror spaced from the bore in a direction opposed to the end surface and coaxial with the bore for reflecting light passing through the bore and circuitry to digitally store a representation of the reflected light.
