Device for detecting a leak of laser |
摘要 |
The present invention discloses a device for detecting a laser leak for electrically detecting a leakage of laser beam due to snapping of the laser guide which is provided for guiding the laser beam to a desired position. A wire or a conductor which is connected to a detector is provided at the circumference of an optical fiber or a coating material of the laser guide. The snapping of the wire by melting or by the variation of the resistance due to raised temperature or by short-circuit of the wire on account of a dielectric break-down of the coated material is electrically detected by the detector. Thus, leakage of the laser beam from the laser guide is strictly detected to secure the safety of an apparatus and an operator.
