Definitions

  • the optical device is designed such that the laser beam provided is refracted, in particular bundled, by the optical device on the path between the laser source and the deflection device.
  • a refractive, in particular a focusing lens, between the laser source and the deflection omitted.
  • the axis of rotation 130 of the micromirror 132 is oriented perpendicular to the plane of incidence of the laser beam 51 provided from the laser source 12 to the micromirror 132.
  • the laser source 12 is oriented such that the laser beam 51 provided would not impact the deflector 114 if the optical device 216 were removed, while in the device 110, upon removal of the optical device 116, the laser beam 51 provided would be remote from the deflector 114 Laser source 12 would hit directly on the micromirror 132.
  • the region of the optical device 416 which has the outer surface 471 may be integrally formed with the region of the optical device 416 which has the second outer surface 172 and the third outer surface 173.
  • the two areas mentioned can also be glued together or joined together in some other way,
  • provided laser beam 51 is designed or set up as a reflected laser beam 52.
