摘要: An electronic focal adjustment system for night vision devices includes a focal adjustment apparatus, a power source apparatus, a button apparatus, and a sensor device. The focal adjustment apparatus may also include a housing that couples to a night vision device. The power source apparatus may communicate with the focal adjustment apparatus, which is configured to interact with an objective lens of the night vision device. A user may set the system to desired focal adjustments. Accordingly, the power source apparatus may send a signal to the focal adjustment apparatus to activate a motor to adjust the system to a user's pre-calibrated focal adjustments.

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.
