Abstract
A stacked disk-shaped optical lens array, a stacked disk-shaped lens module array and a method of manufacturing the same are revealed. The stacked disk-shaped optical lens array is produced by stacked disk-shaped optical lens modules whose optical axis is aligned. The stacked disk-shaped lens module array is produced by a stacked disk-shaped optical lens array whose optical axis is aligned by an alignment fixture, stacked and assembled with required optical element arrays. In the stacked disk-shaped lens module array produced by this method, the lens optical axis is aligned precisely. Moreover, the manufacturing process is simplified and the cost is reduced.
