Z80 Lasers REAL 8W+ Engraving/Cutting Power! DIY CNC Upgrade Module & Kit 100W

  
Z80 Lasers 8+ Watt Z80_8W450B9 450nm Laser Diode This is the most powerful visible light laser diode currently available. Most other sellers are trying to pass off inferior diodes as 10, 15, 20, 30, 40, 80, 90+ Watts, etc. Don't be fooled and do some research.

"Import" watts tend not to be real watts!!! Because the Z80_8W450B9 laser diode is a multi-mode diode you will always get a rectangular spot as opposed to a symmetrical dot. This is a characteristic of multi-mode laser diodes.

You want to focus it so you have the cleanest and thinnest line possible. Don't try to make it symmetrical or you will produce a larger and less powerful spot.

Be aware that the closer you get it to the work the more likely you are to get smoke and/or soot on the lens. It can be cleaned with a very soft.
