Abstract
An improved optical system for scanning optical codes is disclosed. A laser beam produced thereby is a diverging, nearly diffraction free beam and may be used to produce an elongated scanning spot. A laser assembly which may be used to produce such beams and spots, combines various optical functions in structures which are relatively insensitive to temperature change.
