Embodiment

[0014] Embodiment: A reflow-level stacked lens assembly, including a lens protection tube 1 and a lens (lens) 2, the lens is contained in the lens protection tube, and the lens is divided into a first lens 21 and a lens stacked on the second lens. One lens is near some optical lenses 22 of object side, and described first lens is provided with filter (IR glass s) 3 away from object side, and the optical axis of described several optical lenses, the optical axis of first lens and optical filter center on a straight line. Focusing and positioning the lens and the image sensor, stacking several optical lenses to the first lens close to the object side, increasing the number of stacked optical lenses according to different pixel requirements to achieve 300,000 pixels, 1.3 million pixels, 2 million pixels and 3 million pixels (VGA Mega Pixel, 1.3Mega Pixel, 2Mega Pixel & 3 Mega Pixel) and other high-end reflowable stack lenses (Reflowable Stack Lens, RSL) to improve the optical res...

Abstract

The invention relates to a reflow soldering stacked lens component which comprises a lens protective barrel and lenses. The lenses are contained in the lens protective barrel and divided into a first lens and a plurality of optical lens stacked on the first lens close to the object side. The first lens is provided with an optical filter away from the object side. The optical axis of the plurality of optical lenses, the optical axis of the first lens and the center of the optical filter are on a same straight line, the lens and the image sensor focus and position and the number of stacks of the optical lenses are increased gradually according to different pixel requirements to meet the resolution requirement of the higher-order image sensor and improve the optical resolution of the lens with clear orientation, accurate focus position and focal distance from 25cm to infinity. Compared with the traditional lens components, the reflow soldering stacked lens component saves the production cost, is free from focusing, and has simple steps, short industrial chains and easy standardization during packaging process. And the invention has simple structured and easy implement.

Description

technical field [0001] The invention relates to a lens assembly applied to a small camera head, in particular to a lens assembly that can be directly packaged and has clear images without manual focus adjustment. Background technique [0002] As a small part of the camera module, the camera module assembled with other parts is widely used in small electronic products, and with the rapid development of small portable electronic products, our lens components are constantly evolving to more Develop in a simpler and more practical direction. [0003] In the existing technology, our lens assembly generally has the following structure: the lens is installed in the lens barrel, and the lens barrel is equipped with a filter lens in addition to the lens, and the filter lens is installed in the lens barrel by dispensing. There is a screw with a certain pitch outside the lens barrel, which matches the support base, and the focus of the lens can be adjusted mainly by the screw teeth of...
