Abstract:
A laminated wafer lens includes a wafer lens and a spacer substrate bonded to each other. The wafer lens includes a resin section provided on a surface of a glass substrate. The resin section includes lens portions and interval portions, each interval portion provided between adjacent lens portions. The spacer substrate has openings at positions corresponding to the respective lens portions. The lens portions are arrayed in row and column directions in a matrix fashion. The interval portions include first and second interval portions, the second interval portion longer than the first interval portion. The spacer substrate includes interval portions each of which is provided between adjacent openings. The interval portions include third and fourth interval portions corresponding to the first and second interval portions, respectively, the fourth interval portion being longer than the third interval portion.

Abstract:
Provided are a wafer lens production method, an intermediate die, an optical component, a molding die, and a molding die production method. The production method of a wafer lens (1) includes a first intermediate die production step using a die (7), a second intermediate die production step using the first intermediate die (8), and a wafer lens production step using the second intermediate die (9). A first intermediate-die substrate (80) is provided with a depressed section (85) on the surface facing the die (7). When photo-curable resin (84A) is pressed, at least a portion closer to the first intermediate-die substrate (80) among the top (71a) and the peripheral section (77) of the die (7) is arranged in the depressed section (85), and a gap is provided so that the die (7) does not contact with a depressed plane (85a) of the depressed section (85).
Abstract:
An invention for producing a wafer lens is disclosed in which a cured resin is prevented from having projection portions or unfilled sections. The method comprises a dispense step in which resin is dropped onto a die having plural cavities arranged to leave spaces therebetween, an alignment step in which the positions of the die and a glass substrate are adjusted, an imprint step in which one of the die and the glass substrate is pressed against the other, a curing step in which the resin is cured, and a release step in which the glass substrate is released from the die, the steps from the dispense step to the separation step being repeated as one cycle to successively form plastic lens portions on the glass substrate, wherein in the alignment step in each cycle, the cavities of the die are placed between the formed lens parts.
Abstract:
Disclosed is an image pickup device, by which cut resistance at the time of cutting a wafer lens is reduced, high production efficiency is maintained, and excellent optical characteristics are obtained. The image pickup device has a first lens block, a second lens block, a spacer, and a sensor unit. The side surface section of the first lens block, the side surface section of the second lens block, and the side surface section of the spacer are formed on the same plane. A lens cover that covers the first and the second lens blocks is provided in a step formed by respective side surface sections of the first lens block, the second lens block and the spacer, and the side surface section of the sensor unit.

Abstract:
A lens barrel includes: a plurality of lens groups arranged on an optical axis; and at least one reflection surface arranged on the optical axis for bending the optical axis into a plurality of optical axis segments. Among the optical axis segments, at least two lens groups are arranged on different optical axis segments. The lens barrel further includes a lens drive section including a first driving source, for moving the at least two lens groups along the different optical axis segments respectively by using the first driving source.
Abstract:
A camera body to which one of a plurality of interchangeable lenses is selectively attached is provided with: a shake detector 31; a shake compensation mechanism 32; and a controller 30 that compensates for the camera shake by driving the shake compensation mechanism based on the output from the shake detector. The controller 30 has a detector and a selector. The detector communicates with the attached interchangeable lens 20 and determines whether the interchangeable lens 20 itself has a shake compensation mechanism or not. The selector selects, when the detector determines that the interchangeable lens 20 has a shake compensation mechanism, both or one of the shake compensation mechanism of the camera body 10 and the shake compensation mechanism of the interchangeable lens 20 according to a predetermined condition as a compensation mechanism to be used for camera shake compensation.
Abstract:
A camera comprises an angular velocity sensor for detecting camera-shake. The angular velocity sensor takes a certain time to be stabilized after its operation is started. When correction of camera-shake is required during the certain period, it is displayed that correction of camera-shake is not possible. As a result, a photographer using the camera with the camera-shake detection sensor refrains from photographing when correction of camera-shake is not possible.
