What should I do if the marking strength of UV laser water cooled source decreases and the marking is not clear enough?

The decrease in marking strength is a phenomenon that often occurs during the use of UV laser marking machines. I believe this problem is also a headache for many users of UV laser marking machines. The decrease in marking strength of UV laser marking machines will directly affect The marking effect of the product must therefore be resolved immediately.

1. Check whether the laser of the UV laser marking machine deviates from the center point after entering the galvanometer, and adjust the light-emitting position of the laser. Bring it back to the center of the galvanometer.

2. Check whether the resonator of the UV laser marking machine has changed the position of the resonator due to the long use time, and fine-tune each lens of the resonator to achieve the best spot effect.

3. If the current of the UV laser marking machine is not strong enough to deal with 25A, then it is the problem of the krypton lamp, and the krypton lamp needs to be replaced.

4. Check whether the output current of the acousto-optic power supply is low or the position of the acousto-optic crystal is shifted, increase the current of the acousto-optic power supply or correct the position of the acousto-optic crystal.
