A method for press molding a lens array is provided. First, a mold core is provided. The mold core has a first surface having a first alignment formed thereon using a lithography method, and a lens molding surface array and a second alignment formed thereon using an ultra-precision machining method. Then, a substrate is provided. The substrate has a second surface having a third alignment mark formed thereon using the lithography method. The substrate is first aligned with the mold core by aligning the third alignment mark with the first alignment mark, then is further aligned by offsetting the substrate the spacing between the first and second alignment marks to align the center of the substrate with the center of the lens molding surface array. Finally, a molding material is applied on the substrate, then the mold core is applied on the molding material to press mold the lens array.
