Advice on cleaning laser lens
Heyy guys .. I noticed today that my laser's lence is a bit dirty on the incide ... I took the lens off and there was black sud resedue inside .. I don't know from what it could be because it is a brand new laser .. now that I have cleaned the lens with a soft cloth used to clean optics the power of the laser has improved.
Sorry I did not take pictures while cleaning the lens .. I can only show you my clean one
I was just wondering if any of you have an idea what the black stuff could have been and also mabe advice for maintaining clean lenses on the laser head.
probably smoke build up residue. installing a fan that blows smoke away from your work piece can be beneficial.
