SCANNING DEVICE AND SCANNING METHOD

A scanning device, comprising a laser (1) for emitting a light beam (3); a collimator lens (2) with a settable focal length (f1) for focusing a light beam (3) emitted by the laser (1); and a micromirror (4) for modulating the light beam (3) emitted by the laser (1); wherein a light beam distance (L)...

Zusammenfassung:	A scanning device, comprising a laser (1) for emitting a light beam (3); a collimator lens (2) with a settable focal length (f1) for focusing a light beam (3) emitted by the laser (1); and a micromirror (4) for modulating the light beam (3) emitted by the laser (1); wherein a light beam distance (L) from the laser (1) at which a beam radius (d) of the light beam (3) emitted by the laser (1) is at a minimum is settable by setting the focal length (f1) of the collimator lens (2).
