Laser marking machine adjustable mirror beam expander. Laser marking machine beam expander mirror adjustments required: First, to ensure the incident beam expander to be central light well, outgoing light to be in the center of the aperture; beam expander greatly affected the quality of the adjustment has the effect of laser marking . Mainly in: a laser power down; b internal format uneven marking laser intensity; c computer software design center deviate galvo the photophysical center .... d. not play a beam expander effect. On the beam expander tube also has six adjustable screws. If the beam expander offset large, can not fine-tune the calibration, proceed as follows: first, by adjusting the three adjustment screws from the back of the laser light beam expander tube front center of the hole injection; the second step, by Three adjustable front adjustment screw so that the reflected red light and red concentric. When the adjustment to meet the requirements, you can clearly see by the large number of concentric rings return spot shines on the red laser white grating, and concentric. Because of its weak flare, during the second part is recommended in low-light environments. The third step is the first step in the process is repeated. If the beam expander offset much, but also to ensure that the case of the red light collimating coaxial laser and red light, you can observe the red light is roughly from the center beam expander to enter, it is also the center beam expander, the marking software Inside the box draw close to full format, continuous high-speed, playing on a flat metal surface, under normal circumstances should the energy evenly on all sides, if uneven trimming beam expander, remember the number of turns rotating laser laser machine engraving machine, if after trimming the energy difference between the sides in the opposite direction a greater need to adjust the laser laser machine inkjet printer, ultimately each side evenly. CO2 laser discharge tube thickness generally does not affect 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 laser laser machine, per meter length of the discharge tube increases as the power extracted total length. Located in the gas discharge tube glow discharge positive column discharge location work. The region has abundant energy carriers Shiraz, such as electrons, ions, neutral gas fast break, Asia blanket shizhangzi and photon states, is the laser gain region. To this end. Discharge, diameter, length, and straightness degree circle has certain requirements. Most of the production equipment 100w less rigid glass Switzerland. Medium power (10ow-sooty) devices, in order to ensure the power to set rates or Xu common quartz glass produced by noon. Diameter generally 10, or so, when the tube length can be slightly more ancestors. . Around the discharge tube close to the cooling water jacket, which serves to reduce the discharge of the working gas ju degrees. Ensure the device to achieve population inversion distribution in the well to prevent the discharge tube heat burst discharge excitation process. The purpose of adding the water jacket of the working gas is cooled so that the output power is kept stable. Gas discharge tube at both ends and connected to one end of the gas tube that has a small hole and the discharge tube, the other end of the spiral back through the trachea and the discharge tube, so you can make the gas discharge tube and pipe storage in circulation . The gas discharge tube in the trachea with the reservoir at any time in the gas exchange. The outer layer is gas storage pity. Its role is to reduce the one hand, the discharge process of the working gas composition kimono force variation, on the one hand and the discharge tube to enhance the mechanical stability.
