All endoscopes can be equipped with extensive accessories. Many endoscopy accessories manufacturers provide light sources for endoscopes, fiber-optic lighting units, cameras, and monitors for video endoscopes. Different light sources provide illumination of the inspection objects. Cameras get the output of video signals during the application of rigid and flexible endoscopes. With special monitor support, you can enlarge the field of applications.
