Many manufacturers engaged in laser marking processing ask when purchasing equipment: does this machine have a red light adjustment function? What exactly does this’ red light regulation ‘do? Therefore, this media specifically consulted with some equipment manufacturers and compiled several important roles to share with everyone.
1. Resonant cavity optical path
The working principle of a resonant cavity is based on the interference of multiple beams within the cavity, and a basic condition for generating interference is the spatial overlap of the beams, which requires us to accurately control the direction of the beams and couple them to the resonant cavity, that is, optical cavity coupling. For example, semiconductor laser marking machines.
2、 Location
Simply determine the marking position to efficiently carry out processing and production. The indicator light used for laser marking machine marking positioning can be divided into various indication methods according to different marking software, such as marking focus indication, 9-point indication of marking pattern, length and width range indication of marking pattern, and overall simulation indication of marking pattern.
3. Focusing degree
Red light can also be used as the focal point of the laser marking machine, which is an indication of the marking distance (this is a phenomenon where sometimes the red light does not appear, and sometimes it appears again, but only the red light can be seen flickering, but the light cannot be seen). The distance between these two red light points coincides exactly with the distance of the marking airport mirror, so there is no need to use a steel ruler to measure the marking distance every time the product is replaced, reducing the operation steps and improving the marking speed.
