Abstract
A portable laser diode scanning head, aimable at each symbol to be read, emits and receives non-readily-visible laser light, and is equipped with a trigger-actuated aiming light arrangement for visually locating and tracking each symbol. A compact laser diode optical train and an optical folded path assembly, as well as an interchangeable component design and an integral window construction for the head also are disclosed. Also disclosed is an optic means mounted in the laser diode scanning head including a focusing lens and an aperture stop for forming the emitted laser light to have a beam cross-section of an altered size within a working distance range.
