Optical lens cleaning;
A200M fiber laser cutting head has 2 types of protective windows: the one in the top is protective
windows of collimate lens, the other one at the bottom is protective windows of focus lens. When there
are dust or dregs on optical lens, the dust or dregs will absorb heat of the laser beam which can
increase the temperature of the optical lens, then the optical lens can easily be out of shape and result
in bad cutting quality. Thus, the optical lens clearing in regular is necessary. Kindly suggest you do
the cleaning once a week. The components of each protective windows showed as Figure 10.
