Many manufacturers engaged in laser marking processing will ask when purchasing equipment: does this machine have a red light adjustment function? What is the role of this "red light regulation"? For this reason, the editor specially consulted some equipment manufacturers, sorted out several important functions and shared them with you.
1. Adjust the optical path of the resonator
The working principle of the resonant cavity is based on the interference of multiple beams in the cavity. One of the basic conditions for the interference is the spatial coincidence of the beams, which requires us to accurately control the direction of the beams to couple into the resonant cavity, that is, optical cavity coupling. Such as a semiconductor laser marking machine.
2. Positioning
Only when the marking position is set, can the processing and production be carried out efficiently. As the indicator light for marking and positioning of the laser marking machine, according to the different marking software, it can be divided into various indication methods such as marking focus indication, 9-point indication of the marking pattern, length and width indication of the marking pattern, and overall simulation indication of the marking pattern.
3. Focus
The red light can also be used as the focal point of the laser marking machine, that is, the indication of the marking distance (that is, 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 emitted). The distance between the two red light points coincides with the distance of the marking field 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.
