Many manufacturers engaged in laser marking processing will ask when purchasing equipment: Does this machine have red light adjustment function? What is the role of this "red light adjustment"?
1, Adjust the resonant cavity light path
The working principle of the resonant cavity is based on multi-beam interference in the cavity, and a basic condition for interference is the spatial overlap of the beam, which requires us to control the direction of the beam very precisely and couple it into the cavity, that is, optical cavity coupling.
2, Positioning
Only when the marking position is fixed can the processing be produced efficiently.As the indicator light for marking the laser marking machine,according to the different marking software, it can be divided into marking focus indication, the 9-point indication of the marking pattern, marking pattern length and width indication, overall marking pattern analog indication and other various indication methods.
3, Focus
Red light can also be used as the focus of the laser marking machine, which is the indication of the marking distance (this is sometimes the red light does not appear, sometimes red light appears, but only see the red light suddenly dark, but can not play the phenomenon of light). The distance between the two red spots is exactly the distance of laser marking machine f-theta lens. Therefore, it is not necessary to change the marking distance with the steel ruler every time the product is replaced, which reduces the operation steps and improves the distance. Marking speed.
Sino-Galvo Tech.was founded in 2001, and our galvanometer scanners already have got CE, ROHS, FCC and REACH certifications, quality control in accordance with ISO9001 quality system standard, and we exported our products to many countries and regions.We also provide complete marking system including fiber laser marking machine, CO2 laser marking machine, production date batch number serial number laser marking machine and other laser equipment.
