A micro-optical system (20) with autofocus capability utilizing micro electro-mechanical systems (MEMS) to vary the focus of the beam achieving increased depth of field and improved poor quality reading. The disclosed micro-optical system includes a light source (15), a micro-optical element (10) positioned adjacent the light source (15), a detector (32) configured to provide detection information based at least in part on a location of an object, a processor configured to calculate and transmit actuation information, and an actuator (40) configured to adjust the relative spacing of the micro-optical element and the light source based at least in part on the actuation information received.
