How to do that?
Keeping the optics in perfect condition is really easy. A daily quick check of the lens and the mirror at the working head should be part of your daily laser routine. The mirrors in the side panel should be checked once a month. Depending on the material you use you might have to shorten your intervals. Thank to Trotec's InPack TechnologyTM lenses and mirrors are perfectly protected from dust. This reduces cleaning dramatically.
