Dear all, The Argon laser of the Leica SP8X is getting unstable. This has nothing to do with the power break. You can still use it, but you have to restrict it to 20% in the window where you activate it. Running the Argon laser at low output will anyway increase its life span, so from now on, this should be implemented at all times. have fun imaging, d Prof. Dr. ir.
