Abstract: The present invention provides a lens barrel array, a lens array and a method of making the same. The lens barrel array is realized all together in collective operation, and intended to be separated later on to be used as lens barrels of individual module. The lens array including plates, each of which has a hollow portion, attached together and lenses mounted in the hollow portions respectively. The lens array is intended to be separated later on to be used as lens barrels of individual module. The method includes the steps of providing a plurality of plates with hollow portions thereon, installing lenses into the hollow portions respectively, and attaching the plates together to form lens barrel array with a plurality of lens, each of which includes the hollow portion and the lenses, intended to be separated later on to be used as lens barrels of individual module.
