An optical apparatus and an image pickup apparatus capable of reducing an impact force transmitted to an inside without increasing a total length is provided. A frame member which moves forward and backward in the optical axis direction integrally with an extension lens barrel has a recess facing a protrusion of a cam barrel in a radial direction. An elastic member urges the extension lens barrel and the frame member to be away from each other in the optical axis direction. A restriction member holds the frame member with a first gap formed between the extension lens barrel and the frame member in the optical axis direction. A second gap formed between the protrusion and the recess in the optical axis direction is smaller than the first gap.

An adjustable optical lens, a camera module and an aligning method thereof are disclosed. The adjustable optical lens includes at least one lens element and an optical structure element. Each of the lens elements is successively and overlappingly arranged in an photosensitive apparatus of the optical structure element, wherein at least one of the lens elements is configured as an adjustable lens element whose assemble position is adjustable. The optical structure element has at least one adjusting channel and at least one fixing channel for adjusting and fixing the adjustable lens element respectively.

A method for producing a camera module. An objective is aligned with respect to an image sensor and is then fixed in position by being joined to a support that receives the image sensor, a housing that surrounds the image sensor, or an interposed connection structure as a joining partner. The objective is mounted on spacer elements, which are initially still movable, and is then aligned with respect to the image sensor by moving the spacer elements. After the objective is aligned, the spacer elements are welded to the objective and the joining partner. A camera module is also described.

In a frame for lens 20, a main body 21 is urged by the reaction force of an elastic member 24 toward the side on which an upper outer peripheral portion 22a is present, and support portions 23 that are formed on the upper outer peripheral portion 22a are brought into contact with an inner peripheral portion 9 of a stationary tube 5. Thus, the main body 21 is held by the stationary tube 5 without being tilted in the stationary tube 5.

An optical module includes a first bearer and a second bearer. The first bearer includes a first bearing portion and an inclined plane, the first bearing portion is configured to carry a first optical element, and the inclined plane is disposed on a peripheral edge of a first end surface of the first bearing portion. The second bearer includes a second bearing portion and a protruding portion, the second bearing portion is configured to carry a second optical element, a second end surface of the second bearing portion faces the first end surface, and the protruding portion extends from the second end surface to the first bearing portion and is configured to contact the inclined plane. When the protruding portion contacts the inclined plane, the inclined plane does not expose the protruding portion in a direction from the first bearing portion to the second bearing portion.

An optical apparatus includes a first base and a second base, an optical element held by at least one of the first and second bases, and an adhesive configured to adhere the first and second bases to each other. The first base further includes a first recessed portion into which the second base is inserted, a first contact portion contacting the second base, and a groove portion configured to allow at least a part of the adhesive to enter therein. The second base includes a second contact portion configured to contact the first contact portion.

A multi-group lens assembly includes a plurality of lens group units and at least one assembly structure. The assembly structure is for assembling two adjacent lens group units. Lenses in the lens group units are made of any two or three of a glass material, a resin material, and a glass-resin composite material. Alternatively, the lenses are made of only the glass-resin composite material. The lenses can be assembled and adjusted easily and conveniently and have high pixel densities and small TTLs, thereby improving user experience.

Apparatus and associated methods relate to a lens alignment system having opposing end effectors configured to control a position of a rigid lens body with respect to a plane. In an illustrative example, each of the opposing end effectors may engage a corresponding receptacle on respective opposite faces of the lens body. Each of the end effectors may, for example, frictionally contacts each of the corresponding receptacles within a respective portion of each of at least two contact regions. During the engagement, each of the contact regions may, for example, lie on opposite sides of an axis of rotation that extends between the end effectors. In response to at least a predetermined minimum net moment applied to the lens body, the lens body may, for example, be rotatable about the axis of rotation. Various embodiments may advantageously enable precise and/or rapid positioning of the lens body in the plane.

The present technology relates to an imaging device and an electronic apparatus capable of adjusting a focus position and an image stabilization position with high accuracy. There are provided a lens that converges object light, an imaging element that photoelectrically converts the object light received from the lens, a circuit base that includes a circuit configured to output a signal received from the imaging element to an outside, an actuator that drives the lens with a PWM (Pulse Width Modulation) waveform in at least either one of an X-axis direction and a Y-axis direction, and plural detection units that are so disposed as to face plural first coils included in the actuator, and detect magnetic fields generated by the first coils. The present technology is applicable to an imaging device.

The present embodiment relates to a dual camera module comprising a first camera module and a second camera module, wherein: a first magnet unit of the first camera module includes a first magnet and a second magnet, both disposed opposite to each other on a side surface of a first housing; a second magnet unit of the second camera module includes a third to a sixth magnet arranged on four respective corners of a second housing; a third magnet unit is disposed on a side surface of the first housing facing the second housing; the third magnet unit is disposed between the first magnet and the second magnet; and the third magnet unit is smaller than the first magnet and is disposed on a virtual line connecting an optical axis of the first camera module and an optical axis of the second camera module.
