A replacement focusing lens for our High power 450nm blue laser module Kit. Laser lenses are a consumable item. Smoke, resin and debris coat the glass over time, and once a lens is fogged, scratched or burnt you will notice slower engraving, weaker burns and a fuzzy beam spot no matter how well you focus.
 
Lens body diameter: ~8.76mm
Lens body length: ~6.64mm
 
PLEASE NOTE: The Image shown may not look exactly the same as your exact lens, this is fine provided that you are replacing a lens on a CNC3D 15w laser body. 
 
These lenses are specifically designed to fit a CNC3D 15w laser and may not fit other lasers of other sizes or brands. Please check the sizing of your existing lens against the sizing listed here for more details if it will fit or not. We can NOT confirm if they will fit any other 3rd party lasers.
