MJ-CO2 laser printer machine

The laser beam from the CO2 laser is controlled to go through the beam expander, where the beam is expanded to a proper size which can meet the need of marking. The Beam is then reflected on the two f-theta-lenses. The incident angle is controlled by computer and the f-theta-lenses can scan in X- and Y-axis, so that the laser beam is able to deflect. As a result, the laser focus can move on the material to mark according to our needs and the marking process is accomplished. The active laser medium is gas discharge which is air cooled (water cooled in higher power applications) The specific proportions vary according to the particular laser. The population inversion in the laser is achieved by the following sequence: 1. Electron impact excites vibration motion of the nitrogen. Because nitrogen is a homonuclear molecule, it cannot lose this energy by photon emission, and its excited vibration levels are therefore met stable and live for a long time. 2. Collisional energy transfer between the nitrogen and the carbon dioxide molecule causes vibration excitation of the carbon dioxide, with sufficient efficiency to lead to the desired population inversion necessary for laser operation. 3. The nitrogen molecules are left in a lower excited state. Their transition to ground state takes place by collision with cold helium atoms. The resulting hot helium atoms must be cooled in order to sustain the ability to produce a population inversion in the carbon dioxide molecules. In sealed lasers, this takes place as the helium atoms strike the walls of the container. In flow-through lasers, a continuous stream of CO2 and nitrogen is excited by the plasma discharge and the hot gas mixture is exhausted from the resonator by pumps. •Safety advises This product is a classic 4 laser system; it means this kind of product must have an obvious warning label. This product has a certain degree of danger for all users. It’s strongly recommended that you read the user guide carefully before installing and starting the printer The active laser medium is gas discharge which is air cooled (water cooled in higher power applications)The specific proportions vary according to the particular laser.The population inversion in the laser is achieved by the following sequence:1.

It’s strongly recommended that you read the user guide carefully before installing and starting the printer The products of Shanghai Magele Packing Machinery Co,. Ltd are strictly under national standards and laser industrial standards manufactured. This user guide will give you advices preventing from danger to you and your devices, so that you can use this marking system safely. The marking and engraving with this printing system can produce smog. It is suggested that the user set up a smoke device or smoke filtration system of Magele, so that the working environment is not polluted. Before starting this device, please check it with following steps: Power Supply: power is 220VAC; input power is more than 2kW. It is suggested to use a 3-core- cable with 3mm-long-diameter under the international standard which contains neutral wire and a separate ground wire. No vibration source or strong electromagnetic disturb in the surrounding.No dust in the surrounding. (Dust can reduce the lifetime of the mirror.)Room temperature is between 20 and 25. You can install air conditioner to improve the working environment. The EzCad2 software run on an PC with 900 MHz CPU and 256 MB RAM at least. In general, we recommend the fastest PC available. EzCad2 was developed in Microsoft Windows XP and will run in VISTA EzCad2 requires a software security device sometimes known as a 'dongle'. This device plugs into the USB port on the PC. If there is no dongle or the dongle do not install correctly, a caution will appears and the software will work at demo state. In demo state, we can evaluate the software but we cannot save files and cannot control laser device.
