Laser Barcode Reader – A Hign Tech Way To Read BarcodesYou might have come across a barcode reader many a times but may not have noticed it. A barcode reader comes in various forms and one of the popular ones is a laser barcode reader. Yes, a barcode reader is the same machine that the shopkeeper uses to help calculate the total amount of your purchased products. It is the machine that is used to help make your bills whenever you shop. A laser beam is used to read bar codes and extract the contained information. The major difference between a laser barcode reader and pen type readers is that it uses a laser beam. The pen type barcode readers or image scanners consist of an in-built source of light through which they read the data. The laser scanner uses the laser beam as the light source for the same purpose. The working of a laser barcode is almost similar to a pen type barcode reader. Most laser barcode readers employ either a rotating prism or a reciprocating mirror to scan the laser beam. The mirror or prism is used to send the laser beam back and forth across the bar codes. The laser barcode reader includes a photo-diode, which is also present in a pen type scanner. This diode is used to measure the intensity of the light that is reflected back from the bar code. In almost all types of barcode scanners, the light that is emitted by the barcode reader is tuned to a particular frequency and the photo-diode within the reader is designed to read only that frequency of light. A laser barcode reader has a few advantages over an image scanner. An image scanner can read the information from a bar code only from within a distance of four to ten inches away. Whereas, a laser barcode reader scans a bar code even from a distance of 24 inches, which is definitely a comparative advantage. This becomes possible because the barcode reader makes use of lenses to decode the bar code. Additionally, you can position a laser reader at any angle. Another good news is that the latest version of a laser barcode reader can read the barcode even from a distance of 30 feet. You can find various brands of manufacturers that provide laser barcode readers at different prices and with different features. According to your needs, you can choose the one that suits your needs in the best possible manner! A barcode reader is a long time investment and hence it is important to choose the right kind.
