laser (cf. text), shutter open.
Advantages
- Safety at work.
- Extremely quick (<= 10 ms) shutdown of even strongest laser light, can be triggered by persons or obstacles.
- The powerful laser beam, i.e. an invisible YAG laser, is enveloped by a human visible safety laser light. The (partial) interruption of the light triggers the safety shutdown.
- The shutdown is achieved by swivelling a blocking material into the beam instead of shutting down the laser. Thus, a fully active beam can be recovered immediately after the person/obstacle moved out of the critical area.
Applications
- The safety feature can to introduced for all kind of even strongest laser beams.
