| 摘要 |
The invention relates to a tool device, in particular a safety device for circular saws, comprising at least one first emitting device (10), which is provided to emit radiation having a first and at least one second wavelength range (12, 14) during at least one operational process. It is proposed that a central wavelength (16) of the first wavelength range (12) is between 600 nm and 1350 nm, and that a central wavelength (18) of the second wavelength range (14) is between 1150 nm and 200 nm, or between 1200 nm and 1300 nm, or between 1300 nm and 450 nm, or between 1450 nm and 3000 nm. |
