ABSTRACT:
Disclosed are a microlens array, and a method of positioning and aligning the microlens array on another device. Generally, the microlens array comprises an array of injection molded microlens elements, and a supporting flange. Each of the microlens elements has a generally spheroid or spherical shape, and the supporting flange connects together the array of microlens elements to facilitate positioning that array of lenses on a printed circuit board, semiconductor package or wafer. This array is well suited for use with vertical cavity surface emitting lasers (VCSELs); and, in particular, the preferred embodiment of the invention addresses the problem of VCSEL laser array alignment by using arrays of microlenses elements fabricated by injection molding.
