Minisize optical lens

Abstract

The micro optical micro lens comprises: a lens barrel. In the lens barrel, there is a first lens, a first pressure ring, a field mirror, and a second pressure ring in which a magnifier is mounted sequentially mounted. Said first lens is a concave convex lens with a plane table around it; the plane table is supported by the first pressure ring.

Description

Technical field:

[0001] The invention relates to an optical lens. Background technique:

[0002] Optical lens is the core component of video products such as mobile phones, monitors, monitoring system series products, digital cameras, digital video cameras and other optoelectronic products. The size, weight, clarity, illumination and field of view of optical lenses determine the grade of optoelectronic products and market competitiveness. At present, the optical lenses used in domestic and foreign video systems generally have problems such as large size, low definition, high illumination, narrow field of view, low resolution, and blurred images. Invention content:

[0003] The object of the present invention is to provide a micro optical lens with reasonable structure and good imaging quality.

[0004] Technical solution of the present invention is:

[0005] A kind of miniature optical lens, it is characterized in that: there is lens barrel, and first lens, first pressu...

Examples

Embodiment Construction

[0012] A kind of miniature optical lens, has lens barrel 1, and first lens 2, first pressure ring 3, field mirror 4, second pressure ring 5 are housed in lens barrel 1 sequentially, and magnifying glass 6 is installed in the second pressure ring 5 The first lens 2 is a concave-convex lens with a platform 7 around it, and the platform 7 of the first lens is supported on the first pressure ring 3, and the first lens fixing collar 8 is installed on the outside of the first lens 2, and the second pressure ring 5 Threaded connection with lens barrel 1. A first pressure ring support platform 9 is arranged inside the lens barrel 1 . The convex surface of the first lens is coated with a near-infrared film layer 10 .
