How to adjust Laser Lens For CO2 Laser Machine
Training Technical How To Adjust Laser Tube Lens。
Step 1: Adjust the laser current of the CO2 Laser Machine to less than 5, so that the laser power should not be too strong;
Step 2: Put the dimming paper in front of the first lens, and lightly press the test switch with your hand (press and release immediately, you can see the laser spot on the dimming paper), and check whether the spot falls on On the first lens (preferably the middle), if the lens can be found, this step is completed on the upper. If the lens cannot be hit or the lens is deflected, you need to adjust the position or height of the laser tube to meet the above standards.
Step 3: Adjust the optical path between the first lens and the second lens. First put the laser paper in front of the second lens, push the guide rail to the position (a) in the figure, click a test switch to see the spot position. Next, pull the guide rail to position (b) and click the test switch to see if the positions of the two spots overlap. If they overlap and the spot position is within the lens, the light path between lenses 1 and 2 is correct; if they do not overlap, you need to adjust the adjustment screw on the frame behind lens 1 to adjust the two points together.
The fourth step: the adjustment of the optical path between lenses 2 and 3. First push the laser head to the position (c) in the figure, and put the dimming head in front of the small hole of the laser head / lightly press the test switch to look at the light class, then push the head to position (d), and press it again Test the switch to see if the two marks overlap. If they overlap and the two spots are within the small holes of the laser head, the light path is correct; if they are not the same point, you need to adjust the adjustment screw on the back of the frame 2 to adjust it. The above standards. Note: The principle of optical path adjustment between lens 1, 2 and 2, 3 is the same.
Step 5: Adjust the light path between lenses 3 and 4 (one step close to Jian). First remove the lens, put the glossy paper under the laser head and click the test switch to see if the light spot hits the dimming paper in the middle. If it is exactly in the middle, the light path is positive; if the spot is to the right, the laser tube is too low; if the spot is to the left, the laser tube is too high; in these two situations, you need to adjust the height of the laser tube to solve the problem. If the light spot is inside or outside, you need to move the position of the laser head (there are three screws on the laser head, through which you can adjust the inside and outside of the laser head) to achieve the purpose of adjusting the optical path.
Step 6: Install the lens and the adjustment of the light path is completed.
