Description

Lens clamping and adjusting piece

Technical Field

The utility model relates to the technical field of lens equipment, in particular to a lens clamping and adjusting piece.

Background

Along with the progress of technology, people have increasingly demanded photography and image capturing, and have increasingly demanded photography definition and other performance requirements, the focal length of a lens determines the viewing angle and the sense of distance of the photograph, and the aperture determines the light transmission capability and the exposure control capability of the lens. Different lenses have different focal lengths and maximum apertures to meet different shooting requirements. And the optical performance of the lens relates to the aspects of imaging definition, distortion, dispersion, contrast and the like. Different lens types (such as wide angle, standard, long focus, micro distance and the like) have different optical designs and characteristics, and are suitable for different shooting scenes and subjects.

Therefore, when a manufacturer produces a specific image pickup apparatus, it is often necessary to configure lenses (including an in-lens focal length, a maximum aperture, and the like) with corresponding functions, and after the production of the lenses, small deviations in the internal performance of the individual lenses are unavoidable, resulting in that the corresponding image pickup apparatus does not achieve the intended effect after the assembly. The existing adjustment mode is to take out the lens with deviation separately and put the lens into a specific device to detect adjustment.

The specific device is generally large in size, when the space required to be detected and adjusted is small, only small detection and adjustment devices can be used, and the small devices cannot accurately detect the precision of the lenses, so that the usability of the photographing and image pickup device after assembly is directly affected.
