ABSTRACT:
A combination electronic iris and connector for use with a light source, an optical fiber and a CCD, which is optically coupled to the optical fiber, includes a socket, a plug, a heat sink and an electronic iris. The socket has a threaded bore and is mechanically coupled to the light source. The plug is adapted to be coupled to the socket and has a bore for receiving the optical fiber. The heat sink has a disc-shaped portion having a bore for receiving the optical fiber and a threaded stem portion having a bore for receiving the optical fiber. The disc-shaped portion of the heat sink is slidably coupled to the light source and disposed adjacent to the socket. The threaded stem portion of the heat-sink is threadedly coupled in the threaded bore of the socket. The optical fiber is optically coupled to the light source. The electronic iris is disposed within the light source and axially aligned with the optical fiber. The electronic iris is controlled by feedback from the CCD from a feedback circuit.
