Abstract: A motorized optical scanner device (700) of a Light Detection and Ranging (LiDAR) scanning system used in a motor vehicle is disclosed. The motorized optical scanner device (700) comprises a glass-based optical reflector (702) including a plurality of reflective surfaces (704A-E) and a flange (902). The rotatable optical reflector device further comprises an adjustment ring (908) and a metal-based motor rotor body (904) at least partially disposed in an inner opening (920) of the glass-based optical reflector (702). The flange (902) extends from an inner sidewall (912) of the glass-based optical reflector (702) towards the metal-based motor rotor body (904). The flange (902) includes a first mounting surface (922) that is in contact with the adjustment ring (908). The motorized optical scanner device (700) further comprises a plurality of fastening mechanisms (804). The plurality of fastening mechanisms (804) facilitates applying adjustment forces to the adjustment ring (908) to reduce wobble associated with rotation of the glass-based optical reflector (702). When center of a polygon mirror is not perfectly in-line with its center of rotation, tilt angles of polygon facets may change in the process of angular rotation, and the polygon mirror may wobble. During the wobble adjustment process, at least two fastening mechanisms (804), e.g., adjustment screws, may be installed into at least two selected threaded holes (930) in motor assembly (910) to apply adjustment forces, e.g., pushing forces, to the adjustment ring (908) to reduce wobble.
