Abstract

The invention discloses an optical zoom system, comprising an optical sensor, a wafer-degree optical lens module and a focusing motor, wherein the wafer-degree optical lens module is positioned on the optical sensor; the wafer-degree optical lens module comprises at least a transmitting substrate and at least a lens, wherein the lens is arranged on the transmitting substrate; and the focusing motor is positioned between the wafer-degree optical lens module and the optical sensor and is used for moving the wafer-degree optical lens module to enable the wafer-degree optical lens module to be far away or close to the optical sensor.

Description

technical field [0001] The present invention relates to an optical system, and in particular to an optical zoom system. Background technique [0002] With the trend of miniaturization and low-cost modules of electronic products, the emergence of Wafer Level Module (WLM) technology has attracted much attention. The wafer-level module technology mainly enables electronic products to utilize wafer-level manufacturing technology, thereby miniaturizing the volume of electronic products and reducing costs. Among them, the chip-level module technology can also be applied to the production of optical zoom systems, so that the volume of the optical zoom system can be much reduced compared with traditional optical zoom systems, and then can be applied to camera modules such as mobile phones. [0003] figure 1 It is a schematic diagram of an existing optical zoom system. Please refer to figure 1 , the optical zoom system 100 includes a light sensor 110 , an optical lens 120 and a f...
