What Is Laser Barcode Scanner?

- Nov 21, 2018 -

Laser Barcode Scanner is an electronic device that can read and output printed barcodes to a computer, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones.the light source is 650nm visible laser .

It use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the bar code,the laser line use to detect the width of the bars in a barcode and the spaces between them,then reflect to the scanner to decode.

A laser scanner sends out a thin beam of light at the barcode. This beam of light is reflected off the barcode differently depending upon the color of the surface the beam hits. Recall that white is the result of all colors of light being reflected, and black is the result of all colors being absorbed. Of course, due to several factors, even the black on a barcode will reflect back some light. Still, the laser scanner is able to detect the width of the bars in the barcode by sensing the amount of light being reflected by the surface on which the barcode is printed.

The laser barcode reader works well with 1D applications; such as the UPC-A codes widely used in the retail industry and grocery stores. It adapts to distances up to three feet and works well in areas with poor lighting. The laser barcode scanner accomplishes its scanning in one of three different ways: by rastering (capturing lines that cover the scanned area), moving beam (the laser moves across a UPC area a single line at a time), and omnidirectional (multiple beams read barcodes at different angles).

The advantage of the laser barcode scanner is that it can read barcodes even when the barcode or scanner is in motion, quickly and accurately, allowing for fast decodes. Additionally, the laser can project a beam over long distances without spreading out, making it ideal for long distance scanning.

Laser barcode scanners have high precision and accuracy. They are considered to have a good performance because of their scanning range. They have the ability to read barcodes from greater distances and are preferred for non-contact applications.

 Laser barcode scanners can read barcodes at a wider range of distances. they can be kept at a distance from the barcode. Hence, they are mostly preferred for long range scanning.and they can read barcodes of longer lengths,and very easy to handle, Even an untrained operator can use it without any issues.

There are different kinds of Laser Barcode Scanner available from Syble,wired and wireless Handheld Barcode Scanners,please contact us for expert recommend of the most suitable barcode scanner.
