摘要： A glass lens array module with alignment fixture and a manufacturing method thereof are revealed. A glass lens array is produced by multi-cavity glass molding and alignment members are arranged on a peripheral of non-optical area of the glass lens array. Optical axis of each of two adjacent glass lens arrays is aligned by corresponding alignment members and the glass lens arrays are assembled by glue. A spacer is disposed between the two adjacent glass lens arrays to form a preset interval if needed. Thus a glass lens array module is formed after curing of the glue. Thereby the alignment of the optical axis of the glass lens is achieved easily and optical precision is also attained. Moreover, the manufacturing processes are simplified and the cost is reduced.
