What is the difference between Laser mirrors and ordinary mirrors?

These mirrors have a different structure than ordinary mirrors, the components of ordinary mirrors consisting of a piece of glass that is covered with a thin layer of aluminum or silver from the back.

Aluminum transmits light and the glass protects the reflective layer, but unfortunately the light produced by the laser device (infrared light) can not pass through the glass and this layer is located on the front surface of the mirror, so the main difference between Ordinary mirrors and Mirrors used in laser machines is the location of the reflective layer on the glass surface

* How to mirror alignment of the laser device *

Step 1: Adjust the laser tube

Adjust the position of the laser tube using the bases of the laser tube so that the laser beam hits the center of the mirror number one. Note that the angle of the mirrors should be set equal to 45 degrees

Step 2: Adjust mirror number one

Move the Y axis to the closest position to mirror number one, by sticking a piece of paper glue on mirror number two, determine the place of collision of the laser beam on mirror number two, if the laser beam does not collide in the center of mirror number two, with Screws on Mirror No. 1 Do not adjust the laser beam collision center on    Mirror 2.

Now move the Y axis to the farthest position from mirror number one, stick a piece of paper glue on the previous glue that marked the laser beam in the middle of the mirror, see the laser beam again, if the laser beam does not match In the center of mirror number two (the location of the two burns should coincide) Adjust the location of the laser beam in the center of mirror number two using the screws on mirror number one.

* If the above steps are successful, the number one mirror is set correctly*

Step 3: Adjust mirror number two

* These steps are similar to steps number two.

Move the x-axis to the closest position to mirror number two, by sticking a piece of paper glue on mirror number three, determine the place of impact of the laser beam on mirror number three, if the laser beam does not collide in the center of mirror number three, with With the help of the screws on the mirror number two, do not adjust the collision of the laser beam on the center of the mirror number three.

Now move the X axis to the farthest position from mirror number two, stick a piece of paper glue on the previous glue that marked the laser beam in the middle of the mirror, see the laser beam again, if the laser beam does not match In the center of mirror number three (the location of the two burns should coincide) Adjust the location of the laser beam in the center of mirror number three using the screws on mirror number two.

* If the above steps are successful, mirror number two is set correctly*

Step 4: Adjust mirror number three

Attach a piece of paper glue to the end of the nozzle. Using the screws on the mirror number three, adjust the location of the beam on the center of the nozzle.

* If all the above steps are successful, congratulations to you. The mirrors of your laser Machine have been adjusted successfully*
