Product Review
This is a laser head with air-assisted .
With the O-ring in the lens holder, the laser head now can install a 15mm diameter focus lens too.
The mount is capable of hosting a18mm/15mm diameter focus lens and a 20mm diameter reflection mirror.
Focus lens and mirrors are NOT included
Air plug outer diameter: 5.5mm.
This is a great replacement for K40 or D40 that comes with no air-assisted in original packing
NOTE: the laser head is now plated in blue color
