Currently the most commonly used one-dimensional code, book bag food packaging, medicine boxes can see, we have no such a concept is that regardless of the back cover of the book, how bright the food box, medicine box or pattern color, and one-dimensional barcodes are black, and its bottom is generally white or pale-based, is not it? Or you can now get your side of the one-dimensional look at the code. Here, I tell you, the color is very important, that bar code scanning equipment required for color, while natural junior high school physics book book laser spot welding, elementary school said, and black and white is the color of the biggest. As long as there is color, barcode scanners to read out the exact contents of one-dimensional code out. In the previous section, we discuss the one-dimensional code electrolytic iron laser spot welding, and two-dimensional code is the same, the two-dimensional code scanning equipment also to produce color, correct and complete in order to read its contents. This is why the background is white two-dimensional code, its design is black causes. Now we return to the problem of laser marking machine play barcode scanners can identify the one-dimensional bar code and two-dimensional barcodes, as long as we can make out of the bar code laser coders play a larger and background color can be a single light iron laser spot welding, such as playing a dark gray or white or light-colored barcode material inside, or vice versa, in a black or dark-colored tungsten low laser spot welding, play white or light-colored pattern will be able to play a valid barcode. Company products include: fiber laser marking machines, semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine, laser inkjet printer and other industrial laser equipment. CO2 laser marking machine is the innermost layer of the discharge tube, the second layer of water-cooled tubes Xin. The outermost layer of the Ming trachea. In general discharge tube thickness will not impact on the power of Discovery. It is mainly taking into account the effects of diffraction spot size caused by the exclusion of the root should be long past. Tube length of a little rough, a little thin tube short. Discharge power is proportional to the length and brilliant. In a certain length range of the network, each meter length of the discharge tube with the total length of the extracted power increases. Ensure the device to achieve population inversion distribution in the well to prevent the discharge tube heat burst discharge excitation process.
