The method involves determining an adjusted position of a printed circuit board (5) and a collimation lens (6) by focusing and orientation of a laser beam (9), where the collimation lens is spaced from a support member (4) in the adjusted position, where t...

The device has a printed circuit board (2), and a bulb (12) fixed to the board by bonding, where the bulb contains liquid and bubble (13). A determination unit determines horizontality of an apparatus around axes in a plane of the board. The board comprise...

The system has a beam generator in a housing fixed to a positioning unit. A rotation drive module is arranged along a direction coaxial with a central line of the beam. The module includes a brushless motor with a hollow shaft (51) and a stator (53) fixed ...
