摘要:
Ein berührungslos messendes Messsystem mit einem einen Lichtsenderteil und einen Lichtempfängerteil aufweisenden berührungslos messenden Messgerät, zur Positionsbestimmung eines Werkzeuges oder zur Bestimmung der längsten Schneide eines rotierenden Werkzeuges in einer Werkzeugmaschine, wobei dem Lichtsenderteil und/oder dem Lichtempfängerteil eine optische Linsenanordnung zur Formung und Fokussierung eines Lichtstrahls von dem Lichtsenderteil zu dem Lichtempfängerteil zugeordnet ist, wobei die optische Linsenanordnung in einer Linsenfassung aufgenommen ist, wobei die Linsenfassung eine innere und eine äußere, jeweils zylindrische Hülse aufweist, die Linsenanordnung in der inneren Hülse einge-setzt ist, die von der äußeren Hülse zumindest teilweise eingefasst ist, und die Linsenfassung mit der Linsenanordnung in einer Wandung des Lichtsenderteils und/oder des Lichtempfängerteils aufgenommen ist.
摘要:
A structure for a voice coil motor providing controllable lens tilt capability. The voice coil motor structure comprises a lens mount for fixedly mounting a lens (12), a focusing coil (6), a tilting coil (5, 7) and magnets (8-11), wherein the focusing coil (6) and the tilting coil (5, 7) are respectively and fixedly sleeved on the outer side of the lens mount (12). The magnets (8-11) are distributed around the focusing coil (6) and the tilting coil (5, 7) to allow the focusing coil (6) to interact with the magnets (8-11), so that the focusing coil (6) drives the lens mount (12) to move front and back to realize lens focusing. The tilting coil (5, 7) is interacted with the magnets (8-11) to allow the tilting coil (5, 7) to drive the lens mount (12) to tilt and realize lens shift. By virtue of the structure, the focusing and controllable tilting angle of the lens can be realized at the same time. The three-coil structure enables the camera to keep small size and easy to be produced at large scale; impedances of coils are easy to be matched with conventional motor driving circuits; the structure can be widely applied to the current smart cell phones to provide a shooting function same to the medium-end or high-end digital camera.
摘要:
A system and method for coating an optical lens by, for example vapor deposition, that employs a housing or drum having a plurality of apertures that each receives a lens holder assembly. The lens holding assembly configured to hold a standard, uncut optical lenses or lens blanks or, alternatively, to hold cut, non-standard shaped and sized optical lenses.

As electric wires (16) connecting electrode terminals (15 1 to 15 3 ) of a circuit board (10) and electrode terminals (17 1 to 17 3 ) of a connector (18) to each other, an elastic conductor is used. Thus, a pressure applied in injection molding of a holding member (19) to each electric wire (16) is absorbed by the elasticity of the electric wire (16), and therefore, each electric wire (16) can be prevented from being broken through strain deformation, and the electrode terminals (15 1 to 15 3 ) of the circuit board (10) and the electrode terminals (17 1 to 17 3 ) of the connector (18) are prevented from being damaged.
摘要:
An optical mount is disclosed having at least one restraining element for an optic having at least one contact point with a first surface of the optic and at least one force element having at least one contact point with a second surface of the optic, wherein each contact point on the first surface of the optic has a corresponding contact point on the second surface of the optic.
摘要:
A protective case for a portable electronic device including a reading assistance lens assembly, and a case housing. The reading assistance lens assembly includes a housing having a front, back and side perimeter, and at least one lens associated with said housing. The case housing includes a frame, and an extension/retraction mechanism attached to the frame. The frame is configured to provide the reading assistance lens assembly to be extended and recessed within the protective case. The reading assistance lens assembly can be deployed by a sliding assembly, a biased hinge assembly, or a biased spring loaded assembly.
摘要:
The present invention relates to a method, and an arrangement for attaching a lens to a lens holder and to a lens holder for attaching a lens. The method comprises: arranging a fixing arc of a fixing part around a compressible retainer of the lens holder, inserting an attachment portion of the lens into the compressible retainer, and reducing a radius of curvature of the fixing arc, such that the compressible retainer of the lens holder is compressed around the attachment portion, thereby attaching the lens to the lens holder.
摘要:
An insertion part 355 inserted into an insertion hole 255 of a front case 25 in an insertion direction which is a direction of an optical axis and a regulation part 351 for regulating the insertion are formed in a lens holder 35 for holding an image pickup lens 31. Engaging parts 252 and 352 are provided on a surface opposed to a case of the regulation part 351 and on a surface opposed to the regulation part of the front case 25. Projections 3521 of the engaging part 352 are formed surrounding the insertion part 355, and projections 2521 of the engaging part 252 are formed surrounding the insertion hole 255. An interval of the projections of the engaging part 352 is wider than that of the projections of the engaging part 252, and an interval of the projections of the engaging part 252 is formed wider than that of the projections of the engaging part 352. Accordingly, the position of the lens holder relative to the front case is adjusted in a state where the engaging parts 252 and 352 are engaged. The engaged region is bonded with an adhesive and the like in an engaging state where an image pickup lens is positioned at a desired position. The image pickup lens can be precisely mounted at the desired position with airtightness.
