AtomScan Product Family

This chapter gives an overview of features and accessories of AtomScan

scanners:

• Overview of the AtomScan scanner reading system

• Choosing an AtomScan scanner

• Available decoders and accessories

• Package detector and extension cables

The AtomScan scanner uses a visible laser diode for non-contact reading of

bar code symbols. The laser generates a small, concentrated light beam. The

beam is reflected off a 10-sided rotating mirror through the upper window in

the scanner. Light reflected from the symbol comes back through the lower

window, and is detected by a light sensor, which changes it to electrical

signals. The signals are sent to a decoder for further processing.

AtomScan scanners are designed for applications needing a small scanner to

fit into a limited space. It is particularly suited to small packaging and

labeling machines.

Note: AtomScan scanners are designed for use in clean environments.
