Description

Embedded intangible annular microlens zoom lens

Technical Field

The utility model relates to an embedded intangible annular micro-lens zoom lens, and belongs to the technical field of zoom lenses.

Background

The micro lens structure is an array formed by lenses with clear apertures and depth of micron order, and can realize functions of focusing, imaging, beam transformation and the like at micro-optical angles, and the micro lens structure is small in size and high in integration level, so that the micro lens structure forms a new optical system, and the functions which cannot be realized by the traditional optical lens are completed. Microlens arrays have many unique optical properties as a very important micro-nano structured optical component. The optical modulation such as diffusion, shaping, aggregation and imaging of the incident light beam can be realized by precisely controlling parameters such as microlens distribution, focal length, duty ratio, numerical aperture and the like. Therefore, the method is widely applied to the fields of focal plane light collection, large-area display, laser collimation, light calculation, light efficiency enhancement, light interconnection and the like.

The punctiform micro lens is developed vigorously and is widely applied to optical control lenses. However, the point-shaped microlenses use submicron technology to manufacture a plurality of protruding points on the surface of the lens, which results in the difficulty in processing the point-shaped microlenses, inability to polish, and easy abrasion during the production process, so that most of the point-shaped microlenses can only be produced by using a steel mold and using an injection molding method (PC). Most of the high-quality optical resins are produced by using glass molds and a thermosetting method. Therefore, the prior art has the defects of low refractive index, low Abbe number, difficult processing in spectacle stores and the like. In addition, the dot-shaped convex objects are easy to wear, so that the effect of the microlenses is not uniform, and glare stray light is easy to generate.

In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create an embedded intangible annular microlens zoom lens, which has a more industrially useful value.
