When many manufacturers engaged in laser marking process purchase equipment, they will ask: Does the machine have the red light adjustment function? What is the function of this "red light adjustment"? Therefore, I specially seek advice from some equipment manufacturers to sort out some important functions and share them with you.
1. Adjust the optical path of the cavity
The working principle of the cavity is based on the interference of multiple beams in the cavity. One of the basic conditions of the interference is the coincidence of the beam space, which requires us to control the direction of the beam very accurately to couple to the cavity, that is, optical cavity coupling. For example, semiconductor laser marking machine.
2. Positioning
Only when the marking position is fixed can processing and production be carried out effectively. As the indicator light for marking positioning of laser marking machine, it can be divided into marking focus indication, nine point indication of marking pattern, remote indication of marking pattern, overall simulation indication of marking pattern and other indication methods. To different marking software.
3. Focus
The red light can also be used as the focus of the laser marking machine, that is, the indication of the marking distance (sometimes the red light is not displayed, sometimes the red light appears, but only the red light is bright and dark, but the light cannot be played). The distance between the two red light points coincides with the distance of the airport mirror of the mark. Therefore, the steel ruler can be used to measure the mark distance without changing the product once, which reduces the operation steps and improves the marking speed.
