Abstract: A motorized optical scanner device of a Light Detection and Ranging (LiDAR) scanning system used in a motor vehicle is disclosed. The motorized optical scanner device comprises a glass-based optical reflector including a plurality of reflective surfaces and a flange. The rotatable optical reflector device further comprises an adjustment ring and a metal-based motor rotor body at least partially disposed in an inner opening of the glass-based optical reflector. The flange extends from an inner sidewall of the glass-based optical reflector towards the metal-based motor rotor body. The flange includes a first mounting surface that is in contact with the adjustment ring. The motorized optical scanner device further comprises a plurality of fastening mechanisms. The plurality of fastening mechanisms facilitates applying adjustment forces to the adjustment ring to reduce wobble associated with rotation of the glass-based optical reflector.
