Abstract:
A color adjustable light conducting apparatus for use in combination with a standard fiberoptic illuminator having a light source and a light output port, said apparatus comprising:means defining an elongate light conductor;means attached to a first end of said conductor for operably interengaging the output port of the illuminator and introducing light generated by the illuminator into said conductor for transmission therethrough;means communicably connected to a distal second end of said conductor for emitting light from said conductor; andmeans attached to said conductor, between said means for interengaging and said means for emitting, for selectively adjusting the color of light emitted from said conductor, said means for adjusting including an adjuster housing connected to said conductor, said adjuster housing having an interior passageway communicably engaged with said conductor and through which light is transmitted, said passageway having opposing first and second ends, said means for adjusting further including a filter wheel mounted rotatably within said housing and extending across said passageway between said first and second ends thereof, said filter wheel carrying a plurality of light filters, each said filter transmitting a selected wavelength band, said wheel being rotated to position a selected filter across said passageway between said first and second ends thereof such that a corresponding wavelength band of light is transmitted through said passageway, said filter wheel being mounted within said housing such that a peripheral portion of said wheel is exposed from said housing, said peripheral portion being manually engaged to rotate said filter wheel and position a selected filter across said passageway.
