    摘要: An optical device actuator comprises a movable frame (33) including a focus lens (L11); a main shaft guide (40); a piezoelectric element (36a); a weight (36b); a fixed frame (30); a guide holding frame (35); and a spring (36c). The piezoelectric element (36a) imparts vibration to a first end (40a) side of the main shaft guide (40). The fixed frame (30) supports the piezoelectric element (36a) and the weight (36b) disposed on the first end (40a) side of the main shaft guide (40). The guide holding frame (35) supports, in a fixed state, the main shaft guide (40) on a second end (40b) side on the opposite side from the first end (40a) side. The spring (36c) is provided on the first end (40a) side of the main shaft guide (40), and presses the piezoelectric element (36a) along the axial direction with respect to the first end (40a) of the main shaft guide (40) via the weight (36b).

    摘要: The disclosure relates to the technical field of optical systems, and relates to a lens module and an electronic device. The lens module includes a bearing structure, a support frame, a lens barrel, and an adjusting mechanism. The bearing structure includes an upper shell and a base that are connected with each other. In the lens module of the present embodiment, by adopting a bent portion spaced apart from the side wall to cooperate with the focus coil, the internal space of the upper shell can be fully utilized to make the structure between the focus assembly and the upper shell more compact, thereby making the overall structure of the lens module more compact.

    摘要: The present invention is a lightweight lens cell assembly forming a nightvision eyepiece. The lens cell has an integral focusing mechanism and at least one lens element manufactured from a polymer. Because the lens cell is manufactured from a material thermally matched to the polymer and the lens element is integrally connected to the lens cell or connected to the lens cell by an interference fit, the assembly provides significant benefits to both weight and error reduction.

    摘要: An optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, a guiding assembly, and a metallic member. The movable portion is configured to connect an optical element. The optical element is configured to correspond to light reflected by a reflection element, and the reflection element is configured to change a traveling direction of the light from an incident direction to a first direction. The fixed portion includes a base, and the movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The guiding assembly includes a plurality of guiding elements. The metallic member is disposed in the base. When viewed from the incident direction, the metallic member is at least partially located between the guiding elements.
