When purchasing equipment, many manufacturers engaged in laser marking processing will ask: does this machine have red light adjustment function? What is the role of this “red light regulation”?
1. Adjusting the optical path of the resonator
The working principle of the resonator is based on multi beam interference in the cavity, and one of the basic conditions for interference is the spatial coincidence of the beams, which requires us to accurately control the direction of the beams to couple into the resonator, that is, optical cavity coupling. For example, semiconductor laser marking machine.
2. Location
Only by setting the marking position can the processing and production be carried out efficiently. As the indicator light for marking and positioning of laser marking machine, according to different marking software, it can be divided into marking focus indication, 9-point indication of marking pattern, length and width indication of marking pattern, overall simulation indication of marking pattern and other indication methods.
3. Focusing
The red light can also be used as the focus of the laser marking machine, that is, the indication of the marking distance (this is the phenomenon that sometimes the red light does not display, and sometimes the red light appears, but only the red light is bright and dark, but it can not produce light). The distance between the two red light points is just the distance of this marking airport mirror. In this way, it is not necessary to measure the marking distance with a steel ruler every time the product is replaced, which reduces the operation steps and improves the marking speed.
