Method for a laser diode collimator gimbal for precise
adjustment of the laser position inside a laser scanner
Disclosed is a method for a laser diode collimator gimbal for
precise adjustment of laser position inside a laser scanner. Benefits include improved performance and improved
collimator has three set screws to position a round collar. Making a movement
in one axis requires a difficult guess on how much set screw pressure to
relieve or add because the set screws are not aligned with the beam path. The
set screws are all positioned 60 degrees apart, making 90 degree adjustments
precarious and delicate (see Figures 1 and 2).
The disclosed method
is a collimator collar and gimbal (see Figure 3). The method enables the fine
adjustment of the position of the collimator focus lens by fixating the slot on
the inside face of the mounting bracket. The method simplifies the rebuilding
process of the laser scanner heads.
The disclosed gimbal
device provides larger set screws that are aligned parallel and perpendicular
to the laser beam path (see Figure 4). The device provides easy access to the
collimator for adjustment, making laser position adjustments very simple and
timely. The gimbal permanently replaces the conventional mounting bracket. This
device reduces the alignment time required from 20 hours to less than 6 hours.
The disclosed method
provides advantages, including:
