Abstract: A freeform folded optical system that include two freeform prisms with optical power. At least one of the freeform prisms is configured to fold the optical axis twice. Thus, embodiments of the freeform folded optical system fold the optical axis three or four times. Folding the optical axis three or four times in the freeform prisms allows for long focal lengths required for telephoto lens applications without requiring additional lens elements between the prisms. In addition, the configuration of the freeform folded optical system provides reduced Z-axis height when compared to conventional folded lens systems with similar optical characteristics.

Abstract: A lens prism module relates to the field of shooting equipment and includes a fixed base, a rotating base, a mounting base, a prism, and a driving assembly. The rotating base includes rotating shafts rotatably connected with the fixed base and a connecting shaft rotatably connected with the mounting base. An axis of the connecting shaft is perpendicular to an axis of each rotating shaft. An accommodating groove accommodating the connecting shaft is provided on the mounting base. Positioning holes are on a top surface and a bottom surface of the accommodating groove. Two ends of the connecting shaft are separately rotatably disposed on a corresponding positioning hole. On a premise of realizing rotation of the mounting base, a part of the connecting shaft is hidden in the accommodating groove to reduce a volume of an overall structure of the lens prism module, thereby realizing requirements of miniaturization design.
