Technical Field

The utility model belongs to the technical field of optical instrument, concretely relates to long interpupillary distance lens of going into of miniature wide angle high definition.

Background

Lenses of imaging devices such as video cameras and digital cameras are classified into a standard lens, a wide-angle lens, and a telephoto lens according to focal lengths. In general, a wide-angle lens is a short-focus lens, the field angle and the photographing range are larger as the focal length of the lens becomes smaller, and the wide-angle lens can be used to photograph a larger scene or to photograph a full scene within a limited distance.

With the development of technology, image capturing modules are becoming more and more miniaturized, and are also portable because they can be installed in mobile phones, pdas, notebooks and other portable devices. The general wide-angle lens has a mechanical stability maintaining structure, but when the wide-angle lens is applied to law enforcement and evidence collection of official law enforcement personnel such as traffic police, criminal police and law police, the situation of fighting between the official law enforcement personnel and criminals is probably generated, so that the evidence collection equipment can frequently fall down. Because the mechanical stability maintaining structure of the device can only cope with slight shake of the device when the shutter is pressed, when the evidence obtaining equipment falls, the damage of the wide-angle lens is easily caused.
