Abstract
A cylindrical microlens is mounted directly to a laser diode die by using reference edges touching the die at the emitting face and at the top face. Three edges are used to have a stable mounting. The cylindrical microlens, including the reference edges, is manufactured by drawing a glass preform, thus the edges are in perfect register with the optical center of the microlens.
