Abstract

The invention discloses an optical module and a manufacturing method thereof. The optical module is suitable for receiving a first light beam and a second light beam and comprises a substrate, a first optical sensor, a second optical sensor, a first imaging system and a second imaging system. The first optical sensor and the second optical sensor are both arranged on the substrate; the first imaging system is positioned above the first optical sensor; the first light beam is transferred to the first optical sensor through the first imaging system; the first imaging system comprises a first light-transmitting substrate and a first optical component; the first optical component is arranged on the first light-transmitting substrate; the second imaging system is positioned above the second optical sensor; and the second light beam is transferred to the second optical sensor through the second imaging system; the second imaging system comprises a second light-transmitting substrate and a second optical component; and the second optical component is arranged on the second light-transmitting substrate. The optical module has the function of sensing a plurality of images. In addition, therelative position between each optical sensor and related imaging system thereof can be controlled strictly and an overall volume can be reduced.

Description

technical field [0001] The invention relates to an optical module and a manufacturing method thereof, in particular to an optical module with better imaging quality and smaller size and a method for manufacturing the optical module. Background technique [0002] In some special fields (such as medicine or stereo imaging optics), it is often necessary to use multiple camera modules, such as 3D cameras or medical diagnostic instruments. Among them, these multiple camera modules are mostly assembled and pieced together by individual camera modules. Therefore, there are usually disadvantages such as the overall volume is too large and it is not easy to shrink, the distance between the cameras is roughly controlled, and the manufacturing process is complicated. In other words, providing an optical module with a smaller volume, simpler manufacturing process steps, and precisely controlled spacing between cameras (or imaging systems) and a manufacturing method thereof are worthy of...
