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 productivity.

Background

         A conventional 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).

Description

         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.

Advantages

         The disclosed method provides advantages, including:
