Laser Engraver Forum

I have an Xtool D1 pro and have just been reading about the lenses that are used. Is it worth upgrading to something like the Hemsley lens? Apparently the Xtool is plastic and the Hemsley are ground glass coated with an anti scratch. Would I see an improvement in performance that Hemsley promise?

What they mean?
Special lense for engraving can result in better engravings.

If lense not overheating and give good spot is OK.
