the invention relates to a method for calibrating a light source from a medical device, where the light source is connectable to at least one light-guiding fiber, so that the electromagnetic radiation of a defined light energy, either by least partially coupled to the light-orientating fiber. the medical device is connected to at least one calibration port, where the calibration port comprises sensor means for determining a spatial emission characteristic of a light guiding fiber introduced into the calibration port. in this case, the method comprises connecting the light-guiding fiber to the light source, inserting a positioning device for the light-guiding fiber to the calibration port, where the positioning device comprises a receiving channel for receiving the light guiding fiber and also at least one emission opening, where at least one emission opening allows transmission of a light energy from the light guiding fiber in at least one defined spatial direction, introduction of the guiding fiber of light to the receiving channel of the positioning device, coupling the electromagnetic radiation of a defined light energy to the light guidance fiber, determining the spatial emission characteristic of the light energy of the light guidance fiber in the region of the calibration door as a real emission characteristic, determining a desired emission characteristic of the light energy of the light-orientating fiber in the region of the door d and calibrating the light energy coupled to the light guiding fiber by means of the sensor means, and comparing the actual emitted characteristic to the desired determined one. if the actual emission characteristic corresponds to the desired one, the method furthermore comprises releasing the light-guiding fiber for additional use, and if the actual emission characteristic does not correspond to the desired one, producing an error message.a invenção se refere a um método para calibrar uma fonte de luz de um dispositivo médico, ond
