Preferably, magnet ring is provided with the laser level, the magnet ring is connected with the miniscanning eyeglass, when described
When miniscanning eyeglass moves, the magnet ring slows down the vibrations of the miniscanning eyeglass by electromagnetic damping.Existing laser
For the cassette mechanism structure that collimation apparatus uses for drop hammer type, such purpose is to ensure that the movement entirety posture comprising laser emitting module
Keep vertical, so that it is guaranteed that the laser rays projected is not influenceed that any inclination occurs by placed side.Do not occurred before this
The laser level of micromirror systems is carried, it is due to that dither can occur at work for micromirror systems to a certain extent to have, this
Kind vibration will have an impact to the sash weight structure of laser level and cause rocking for certain amplitude.Therefore, this patent provides
Scheme be enclosure interior add magnet ring, the influence that micro mirror dither is brought is overcome by electromagnetic damping.
