Hand-held scanner is the simplest and least expensive barcode scanner available. It can be CCD or laser. CCD scanner is "human powered," which means that it must be held at the proper angle.
CCD barcode scanners use an array of tiny light sensors lined up in a row in the head of the barcode reader. But most CCD scanners have two primary limitations. First, it has a short "read" range, and a limited width. Laser hand-held scanner is the most popular bar code scanner. A laser bar code scanner need not be close to or touch the bar code to do its job. A standard range laser bar code scanner can read a bar code from about 6 to 24 inches away, and a long range scanner can read bar code from about 2 to 8 feet away. An extra long-range scanner can read a bar code 30 feet away. Laser barcode scanners vary in price from $200 to $2,000 and come in a variety of models. They can use single-line scan pattern or multiple line scan pattern.

Metrologic's MS5145 Eclipse is a single-Line, hand-held laser scanner. Equipped with Metrologic's patented CodeGate technology, the MS5145 Eclipse can be used in a wide variety of appications. CodeGate technology allows the user to easily target the desired barcode and complete the data transmission with a simple press of a button.
With Metrologic's state-of-the-art scanning technology embedded inside, the MS5145 Eclipse has a longer working range and a wider scan field than a typical CCD barcode scanner. The width of the scan line grows as the scanner moves further away from barcodes. In addition, the laser beam pulses, which makes lining up barcodes easy.
