Abstract
The present invention is related to a microminiature lens module and a lens device with the microminiature lens module. The microminiature lens module is applied in the lens device in order to decrease the entire outer diameter of the lens device. The microminiature lens module comprises a containing base and a lens set, wherein the containing base has a through hole, and an inner thread is located on a partial inner wall of the through hole. A radius with the inner thread of the through hole is smaller than a radius without the inner thread of the through hole. The lens set is female-connected to the through hole. An outer thread is on an outer rim of the lens set where relative to the inner thread, and the outer thread collocates the inner thread. A radius with the outer thread of the lens set is smaller than a radius without the outer thread of the lens set. As a result of the containing base collocating the lens set, the entire outer diameter of the lens module can be effectively reduced so as to microminiaturize, simplify, and easily assemble the lens module.
