Red laser barcode scanner with distinction 1) red light emitted by the scanner is a very thick line (intermediate rough, two small), farther from the scanner to the bar code scanner, the red light is thicker, the scanning success rate The lower the gun with a red bar code scanning bar codes generally have a very close distance to sweep out. 2) is emitted from the laser scanner is a very thin, very uniform laser line, laser gun reading ability of a lot stronger than red light guns, laser guns can be very far away from the bar code is scanned, good performance laser scanner, or even In half a meter outside the scanning laser bar code scanner much money, but red is not far more than 20 cm. As long as the current red laser can read bar codes, so now is the laser scanner on the market and red light. Construction scanner free POS system in recent years to bring huge benefits businesses, construction of the system is also inseparable from the bar code scanner, bar code as input connected to your system link, barcode scanner plays an irreplaceable effect. Under the user the choice of reliable and affordable scanner price performance in the case, we must first understand how to choose scanner, scanner which classification. Here's what the scanner of classification, the most important business applications, there are three: CCD scanner, laser handheld scanner and the whole point of the laser scanner. A, CCD barcode scanner CCD barcode scanner is the use of optical coupling (CCD) principle of how to use the bar code scanner, barcode printing pattern imaging scanner, and then decoded. Advantages are: no long shaft, motor, life; cheap. When choosing CCD scanner, the most important are two parameters: the depth of field because the imaging principle is similar to CCD camera, if you want to increase the depth of field, to increase the corresponding lens, so that the CCD size is too large to maneuver. Excellent CCD should not be close to the bar code can be read, and moderate size, comfortable operation. Second, the hand-held laser bar code scanner laser handheld bar code scanner is the use of laser diodes as a light source of a single line scanner, which mainly rotating mirror and chatter mirror two. Commercial enterprises in the choice of handheld laser bar code scanner bar code scanner, the most important to note that the scanning speed and resolution, while the depth of field is not a key factor. Because when the depth increased, the resolution will be greatly reduced. Excellent hand-held laser scanner should be high scanning speed, fixed depth of field high resolution. No high bar code scanner sweep _ _ scanner scanning sensitivity, quality assurance provided by the Guangzhou City State Association Information Technology Limited.
