Abstract

A laser radiation-guiding device including: a laser including a control unit; ports for connection of one module each, it being possible that laser radiation may exit at the ports. The device further can include joining part sensors respectively assigned to a port and whose electrical condition depends on whether a predetermined joining part is spaced apart from the respective port by less than a maximum distance in a predetermined orientation relative to the respective port, and an evaluating unit connected to the joining part sensors via a signal link that detects the electrical conditions of the joining part sensors and, depending on the detected conditions, emits a control signal to the control unit of the laser or to a laser radiation-blocking unit, by which emission of eye-damaging laser radiation to the ports of the device can be prevented inhibited.
