Summary
The barcode scanning gun is a widely used barcode recognition device. In terms of light sources, scanning equipment can be divided into two types: red light and laser. Although both types of scanning devices can scan and recognize barcodes, there are some significant differences between them. The following will briefly introduce the difference between red light and laser Barcode reader, so that you can have a clearer idea when selecting Barcode reader.

The following will briefly introduce the difference between red light
and laser Barcode reader, so that you can have a clearer idea when
selecting Barcode reader.
Differences in light sources
The light emitted by the red light scanning gun is a thicker line, with a thicker center and thinner ends. The farther the scanning gun is from the barcode to be scanned, the thicker the red line, and the lower the scanning success rate. The laser scanning gun emits fine and uniform laser lines, and the reading ability of the laser gun is much stronger than that of the red light gun. A high-performance laser scanning gun can even scan half a meter away.
Scanning distance difference
The red light scanning gun usually needs to be very close to the barcode to scan, far less than 20cm. The scanning distance of the laser scanning gun can reach over 30CM, and a laser scanning gun with good performance can reach 50CM.
Changes in scanning accuracy
The scanning accuracy of the red light scanning gun is relatively low, while the scanning accuracy of the laser scanning head is relatively high. Therefore, for some relatively small barcodes, the laser scanning head can also scan, but the red scanning head cannot recognize them.
Application Scenario
For barcode scanning with low requirements and thick and clear barcodes, a red light barcode gun can be selected to reduce costs. If you have higher requirements for scanning efficiency or need to scan finer barcodes, then a laser scanning gun is a better choice.
To sum up, when selecting Barcode reader, we need to consider the differences between different types and applications. If you have any scanning requirements, please contact our company.
