Abstract
We report the design of a vertical cavity surface emitting laser (VCSEL) focusing module, suitable for barcode scanning applications. The dimensions of the plastic lens housing are precisely controlled to set the distance between the laser and the focusing lens, without the need of alignment. Measurement results of prototype devices are also reported.
