Inquire

  When many manufacturers engaged in laser marking process purchase equipment, they will ask: does this machine have red light adjustment function? What is the function of this "red light adjustment"? For this reason, Xiaobian specifically asked some equipment manufacturers for advice, sorted out several important functions and shared them with you.

  1. Adjust the cavity optical path

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

  2. Positioning

  Only when the marking position is fixed 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, long and wide range indication of marking pattern, overall simulation indication of marking pattern and other indication methods according to different marking software.

  3. Focus

  Red light can also be used as the focus of laser marking machine, that is, the indication of marking distance (this is the phenomenon that sometimes red light does not display, sometimes red light appears, but only the red light is bright and dark, but can not play light). The distance between the two red light points coincides with the distance of this marking airport mirror, so that the marking distance can be measured with a steel ruler without replacing the product once, reducing the operation steps and improving the marking speed.
