A method for examining the light and/or image transmission properties of an endoscopic or exoscopic system having the components endoscope or exoscope, light carrier, light source and camera, wherein at least the endoscope or exoscope is taken from a first supply quantity of endoscopes or exoscopes and/or at least the light carrier is taken from a second supply quantity of light carriers, wherein the endoscope or exoscope is provided with an identifier and/or the light carrier is provided with an identifier, wherein the identifier or the identifiers contain/s identification data that individualizes the respective endoscope or exoscope and/or the respective light carrier, wherein the components are connected to each other so as to be ready for operation in the form of a current component combination. The method comprises the steps of: capturing the identification data of the endoscope or exoscope and/or the light carrier, capturing at least one transmission parameter of the current component combination, storing the identification data and the captured at least one transmission parameter. Also described is an apparatus for carrying out the method.
