Abstract
Method for passively aligning micro-optical lenses with other elements, and devices resulting therefrom. The method taught herein is particularly well suited to effect the passive alignment of cylindrical microlenses with other elements or devices, such as laser diodes. Cylindrical microlenses formed according to the principles of the present invention include at least one alignment member including at least one alignment surface. Urging the cylindrical microlens into intimate mechanical contact with the element to which it is to be attached, and its attachment thereto results in micro-optical devices formed with a minimum of skilled labor, which devices reflect a superior degree of optical perfection.
