Micro lens and micro lens array

Abstract

The invention provides a micro lens which comprises a transparent base plate, a first antireflection layer, a first optical part anda first extinction film, wherein the transparent base plate is provided with a first surface and a second surface opposite to the first surface; the first antireflection layer is arranged on the first surface; the first optical part is arranged on the first antireflection layer; and the first matt film is arranged on the first antireflection layer and surrounds the first optical part. The invention also provides a micro lens array which can be cut into a plurality of the micro lenses. The micro lens is provided with the matt film and the antireflection layer, thereby being capable of preventing the micro lens from generating glare and ghost images in the imaging process.

Description

technical field [0001] The invention relates to the field of optical components, in particular to microlenses for miniaturized electronic equipment. Background technique [0002] In view of the fact that portable and lightweight portable electronic devices are increasingly favored by consumers, research on the miniaturization of various components has become a research hotspot for researchers, and microlenses are one of them. A microlens is an extremely small lens that can be used in optoelectronic components such as digital cameras, mobile phones or solar cells. [0003] Due to the immature manufacturing process at present, the microlenses that have been used still have many shortcomings, especially the images formed by some microlenses appear to be white and haloed, mainly because the surface of the lens will reflect a part of the incident light. Light, the light reflected by each lens is reflected multiple times inside the lens and camera to become stray light, which cau...

Problems solved by technology

[0003] Because the current manufacturing process is immature, the microlenses that have been used still have many deficiencies, especially the images formed by some microlenses appear to be white and haloed, mainly because the surface of the lens will reflect a part of the incident light. Light, the reflected light of each lens is reflected multiple times inside the lens and camera to become stray light, which makes the image sensor receive unnecessary light signals, resulting in the above problems, generally known as glare or ghost
