Yesterday we provided information about bar code imagers and the applications they’re best suited for. As promised, today we’re taking a closer look at laser bar code scanners.
Laser bar code scanners read bar codes with a laser beam that is moved back and forth across a code by oscillating mirrors. Laser bar code scanners can only read 1D bar codes and not 2D symbols like imagers. One of the major advantages that laser scanners have over linear imagers is their read range. Laser scanners are capable of reading up to 36 feet away and their narrow beam can support a wide variety of depths of field. Fixed position laser scanners also boast a snappy scan speed of about 600-1800 scans per second. The benefits that laser scanners offer make these devices perfect for applications such as:
- Long-range scanning in warehouses or distribution centers
- Stationary scanners for conveyor belts
