Abstract
A light intensity control device for an endoscope or similar instrument comprising a light source, a fiberoptic cable connected at one to the light source, and a non-electrical diaphragm assembly connected between the end face of the fiberoptic cable and the end face of the fiberoptic bundle within the endoscope. The diaphragm assembly comprises an adjustable opening for receiving light from the end face of the cable for the transmission of light therethrough. A solid member of transparent material between the adjustable opening and the end face of the fiberoptic bundle within the endoscope transmits the light from the cable to the endoscope.
