How to adjust the red light of 355 nm Ultraviolet Laser marking machine

Many manufacturers engaged in laser marking processing will ask when purchasing equipment: Does this machine have a red light adjustment function? What exactly does this "red light adjustment" do? To this end, the editor specifically asked some equipment manufacturers for advice, sorted out several important roles, and shared them with everyone.

1. Adjust the optical path of the resonant cavity

The working principle of the resonant cavity is based on the interference of multiple beams in the cavity, and a basic condition for interference is the coincidence of the beam space. This requires us to very accurately control the direction of the beam to couple into the cavity, that is, light-cavity coupling. For example, semiconductor laser marking machine.

2. Positioning

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, it can be divided into marking focus indication, 9-point indication of marking pattern, indication of length and width range of marking pattern, and overall marking pattern according to different marking software. Various indication methods such as analog indication.

3. Focus

La luz roja también se puede utilizar como punto de enfoque de la máquina de marcado láser, es decir, la indicación de la distancia de marcado (a veces, la luz roja no se muestra y, a veces, aparece la luz roja, pero solo se muestra la luz roja). parpadeando Está oscuro, pero el fenómeno de no mostrar luz). La distancia de superposición entre los dos puntos de luz roja es exactamente la distancia del espejo del aeropuerto de marcado. De esta forma, no es necesario utilizar una regla de acero para medir la distancia de marcado cada vez que se cambia el producto. Se reducen los pasos de operación y se mejora la distancia. Velocidad de marcado.
