How to adjust the laser light path

Note:

● When the device leaves the factory, the optical path has been precisely adjusted to the best state. If you are not sure whether the optical path of the device has shifted, please do not adjust the optical path lens knob or locking screw at will.

● Once the optical path locking screw or knob is adjusted, the optical path of the device may shift. If it shifts, you may need at least 4 hours to readjust the optical path of the device.

2.Adjustment steps

Note：

       Please stick the double-sided tape on the front of the frame to be adjusted, then move the laser head and lightly press the shot button to adjust the optical path.       

   During this process, please carefully observe the changes in the optical path.       

①Adjust the light path from one reflection to two reflections

Stick the double-sided tape to the front of the second mirror frame. 

​

    That is, adjust the light source points 1 and 3 as shown in the figure below to coincide with each other.

                                                                                                                                                                                                                             

      A.Adjust the overlap of ① and ③ light spots 

                                                                                                                                                                                                                  

         When a large deviation occurs, such as the following:

         

         a.At this moment, the light spot is offset to a large extent, and it is necessary to adjust the bottom bracket to make the light spots roughly overlap:                                                        After loosening the fixing screws of the black bracket, start adjusting the upper reflective frame. During the adjustment process, you need to fix the screws               while   fine-tuning the frame to ensure that the light spots roughly overlap. After tightening the screws on one side, check if there is any deviation. When adjusting, you can observe the direction of movement of the light spot when tightening, and push the frame to the opposite direction accordingly, while fixing the frame until the lenses   roughly overlap.

       

          

       The light spots roughly overlap:

                                                        

                                                                                                  

            b.Tighten the three gold nuts on the outside of the lens and the lens will move back, ensuring there is about 1 cm gap between the lens and the frame.

             If the distance between the lenses is about 1 cm, there is no need to tighten the nut again.           

            

         c.Use an M2.5 hexagon wrench to loosen the silver-white nut of the frame

            

           

d.Adjustment Instructions:

In the figure, when screw No. 1 is rotated clockwise, the light source will move downward; when screw No. 2 is rotated clockwise, the light source will move to the right; when screw No. 3 is rotated clockwise, the light source will move to the upper left (counterclockwise rotation will move the light source in the opposite direction). After each fine-tuning of the screw, please slightly tighten the silver-white nut to prevent the light source from shifting a second time. Adjust these 3 screws until the front and rear light sources coincide at the same point.

    

   

       e.After the overlap, please be sure to tighten all the screws on the frame.

       

3.Adjust the optical path from the second reflector to the third reflector

        Stick the double-sided tape to the front of the three-mirror frame.

     

        
        That is, adjust the light source points ①, ②, ③, and ④ in the figure below to overlap and be at the center point.

         

A. Adjust ① and ② light source points to basically coincide

         

        a.Use an M2.5 hexagonal wrench to loosen the two fixing screws of the second mirror frame.

          

         

        b.Move the frame:

Gently move the second mirror frame, move the laser head back and forth, and press the point shooting button to let the laser hit the light source points ① and ②. After the front and rear light spots appear on the third mirror frame, fix a screw and gently swing the second mirror frame to make the light source points ① and ② basically overlap. After overlap, tighten the screw.

           

          

B.Adjust the overlap of light source points ①, ②, ③, and ④

            a.Use an M2.5 hexagon wrench to loosen the two silver nuts on the frame.   

         

             

                   

           

       b.Adjustment Instructions:

In the figure, when screw No. 1 rotates clockwise, the light source moves downward;

When screw No. 2 rotates clockwise, the light source moves to the right;

When screw No. 3 rotates clockwise, the light source moves to the upper left (counterclockwise rotation moves the light source in the opposite direction).

After each fine-tuning of the screw, please slightly tighten the silver-white nut to prevent the light source from shifting a second time. Adjust these 3 screws until         ①, ②, ③, and ④ light sources overlap.

     

      

   

C. Adjust ①, ②, ③, ④ light source points to the center pointa.

                 a.When there is a left-right deviation from the center point, adjust it by adjusting the two-mirror frame

            

          I.Use an M2.5 hexagon wrench to loosen the two silver nuts.

           

          II.Gently push the second mirror frame. If it is biased to the left, move it to the right, and if it is biased to the right, move it to the left, until it is adjusted to the                   center.

          

               b.When there is a height deviation from the center point, the laser height needs to be adjusted.

                 

            i. Use an M2.5 hexagonal wrench to loosen the two Jacking bolts on the laser base      

                 

          ii：Turn this knob clockwise to raise the laser tube, and counterclockwise to lower it. After adjustment, tighten the bottom jacking bolt.     

            Note: The front and rear heights of the laser should be kept consistent, and the top screws on both sides should be tightened.

            

 D.Adjust verticality

 Adjust the burst power to 60% and burst through 10×10mm acrylic. Visually check whether it is vertical. 

            

      a. If the verticality is to the left, the laser needs to be raised; if it is to the right, the  laser needs to be lowered.

          

4. Next Steps

          After completing the adjustment, make sure all fixing screws are tightened and install all door covers and tighten the screws.
