Parts of a rigid laparoscope

Light post – Fiberoptic light cords attach to the scope here.
Light fibers – Glass fibers that carry light from the light post to the distal end of the scope.
Objective lens system – A collection of lenses, windows, and/or prisms located at the distal end of the scope. The distal objective can be manufactured at angles ranging from 0° to 120°, which enables the operator to see areas that might otherwise be out of view.
Lens train – A series of glass rod lenses and spacers that transfer the image through the shaft.
Shaft – Stainless steel tube that houses the lens train.
Ocular lens assembly – The focusing lens of the scope located near the proximal end of the scope.
Eyepiece – The eyepiece is located at the proximal end of the scope. The image can be viewed through the scope, or the eyepiece can be attached to a camera coupler to view the image on an external monitor.
