Description
Technical Field
The invention relates to a lens group and a lens module comprising the same.
Background
Generally, in the assembly of a lens, a plurality of lenses are mounted in a barrel base by means of tight fitting or adhesive bonding, so when the roundness of the barrel base or each lens is not good, problems such as relative shift of central axes of the plurality of lenses or deformation of surface shape of each lens are easily generated, which affects the optical performance of the lens and further reduces the production yield.
In order to solve the above problems, in the conventional lens, the two adjacent lenses are provided with corresponding concave-convex structures to facilitate alignment connection. However, the aforementioned assembling method does not consider the local stress direction of each lens, and the mutual bearing position of the lenses is easy to be inclined and deformed during the actual assembly, so that the problems of the relative shift of the central axes of the plurality of lenses or the surface shape stress deformation of each lens cannot be effectively overcome, and there is a drawback to be improved.
Therefore, there is a need to provide a novel and advanced lens set and a lens module including the same to solve the above-mentioned problems.
