Detailed Description

To facilitate an understanding of embodiments of the invention, embodiments of the invention are described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the examples of the present invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The inventor of the present application finds that the fixation of the existing lens generally requires the position limitation and the support of the bracket 1000. Taking the structure of the double-layer compound eye 2000 as an example, especially a fragile glass lens, the bracket 1000 and the two compound eyes 2000 are generally bonded together by glue, and then are used as a component to be screwed and fixed with the housing 3000 by screws, as shown in fig. 1, 2 and 3.

The distance or focal length of the two compound eyes 2000 is determined by the different heights H of the bracket 1000, as shown in fig. 2. If there are multiple requirements for height H, multiple versions of the rack 1000 may be derived. If the lens is enlarged or reduced, the bracket 1000 also needs to be correspondingly matched with a new design, and a plurality of brackets 1000 are produced and difficult to unify. The high-precision bracket 1000 is high in cost and large in occupied ratio.
