Replacing The Lens - BOSSLASER LS Series Operator's Manual

Replacing the Lens

Lenses are one of the few parts of the laser that will need regular maintenance and cleaning. Cleaning the lens is simple
when done often but can become difficult or not possible when rarely done.
✎Note: The cleanliness of your lens can greatly impact the cuts and engravings that you are trying to accomplish with
your laser. If the lens is obstructed with scratches or a film of char, it will not produce a good quality engraving or cut.
The lens is small, about 20mm in diameter and two distinct sides, one concave and one convex. When re- installing the
lens, the convex side (curved/ rounded side) should always face up in the laser head. (Towards the sky, not towards the
worktable)
As shown in Figure 28, the lens assembly consists of two main parts, the lens housing, and the nozzle. There are also three
components of the lens housing which are the lens, washer, and slotted ring nut.
To remove the lens or replacement of cleaning, loosen the friction set screw on the main lens housing while holding the
lens tube to ensure that it does not fall and get damaged. After loosening the screw set, remove the lens tube from the
housing as shown in Figure 28.
Your machine came with a "Lens Removal Tool" which should be in the toolbox, this will remove the slotted ring nut. The
tool will look like scraper rather than a screwdriver, its width is designed to fit inside the lens tube and fill the slots. Be
careful not to let the tip of the removal tool slip and scratch the lens.
