How to deal with the contamination of the focusing lens surface of laser marking machine?

in Blog, ,

When the marking effect of the laser marking machine is not good, you should carefully check whether the surface of the focusing lens is contaminated.

If the equipment is used for a long time, the dust in the air will be adsorbed on the surface of the lower end of the focusing lens, which will reduce the power of the laser and affect the marking effect in the light case; in the heavy case, it will cause the optical lens to overheat and burst.

If the focus lens surface is contaminated, the focus lens should be removed to clean its lower surface.

How to Disassemble?

Remove the focusing lens with special care, and be careful not to damage or drop it.

Also, do not touch the lens surface with your hands or other objects.

How to clean it?

The cleaning method is to mix absolute ethanol (analytical pure) and ether (analytical pure) in a ratio of 3:1, use a long fiber cotton swab or lens paper to infiltrate the mixture, and gently scrub the lower surface of the focusing lens.

Every time you wipe one side, you must replace the cotton swab or lens paper.
