Light sources, cameras and recording devices
There are two major types of light source available, the cheaper tungsten-halogen and more expensive, rare-earth xenon.
Halogen is sufficient for rigid endoscopy using the eyepiece, but the xenon source is preferred for documentation.
More powerful light sources are essential when dealing with video endoscopy and the reduced light transmission of fine flexible endoscopes.
The light source is connected to the endoscope via a flexible, fiber-optic cable. The efficiency of light transmission is reduced as the cable length increases.
A xenon light source with a dedicated endoscopy camera and some form of documentation capability (e.g. video tape, digital video, digital still image capture, still image print-out) is recommended.

Endoscopy cameras attach to the eye-piece and greatly improve endoscopic ability. Left - basic cameras come with a focusing ring (courtesy of Karl Storz), right - more advanced models possess focus and zoom functions, and a variety of other digital features.
 
Recording is important for case records and educating/marketing.
The new AIDA system permits storage of digital stills and video. The system is very user-friendly and can be operated by foot-pedal or a pre-programed camera.
