MICrO-OPTICS Micro Lens Array Milling on Large Wafers

2009-12-17 · Micro Lens Arrays (MLA) containing thousands of lenses with an aspheric shape and a precise position on large sub-strates are used in sensor devices directly or as master moulds for the low-cost rep-lication of micro lenses in an array. They have to fulfill the high requirements in wafer scale manufacturing of small optics. This high volume manufacturing method for low-cost but effective micro optics re-lies on the sandwich-like assembly of the sensors and optical components like lens-es as well as mechanical components like apertures and spacers on wafer level. Af-ter joining all components the dicing re-sults in a batch of wafer level cameras for the use in cellular phones or webcams.Micro Lens Arrays
