Abstract

An optical module comprises a first bearing seat and a second bearing seat. The first bearing seat comprises a first bearing part and an inclined surface, wherein the first bearing part is used for bearing a first optical assembly, and the inclined surface is arranged at the periphery of a first end surface of the first bearing part; the second bearing comprises a second bearing part and a protruding part; the second bearing part is used for bearing a second optical assembly; the second end surface of the second bearing part faces the first end surface of the first bearing part; the protrudingpart extends out from the second end face of the second bearing part towards the first bearing part and is used for making contact with the inclined face, and when the protruding part makes contact with the inclined face, the protruding part is not exposed out of the inclined face in the direction from the first bearing part to the second bearing part.

Description

technical field [0001] The invention relates to an optical module, in particular to an optical module which can simplify the assembly process. Background technique [0002] A general optical module usually includes a light source and a lens, and during the assembly process of the optical module, it is often necessary to adjust the position of the light source relative to the lens (or the position of the lens relative to the light source) to achieve optical design. Therefore, a plurality of screws corresponding to the directions to be adjusted (such as X, Y, and Z directions) are often provided outside a seat carrying the lens, and the user can move the seat by turning the screws, thereby adjusting the relative orientation of the lens. at the position of the light source. [0003] However, the above-mentioned assembling process is cumbersome, and is only applicable to optical modules with low requirements for adjustment accuracy. In order to satisfy the optical module with ...
