LightobjectCO2 laser head lens/mirror mounting kit
This is a laser head kit with air-assistance. The mount is capable of hosting 18mm focus len and a 20mm reflection mirror. Air tube fitting is 6mm in diameter.
A very reasonably priced upgrade for the standard laser head with very good build quality.
I only have two remarks, which resulted in me deducting a star from this rating:
1.) Changed lens position: With this laser head the lens is positioned about 8mm higher than in the standard head. My machine has a fixed table height, so some change needed to be made in that aspect as well.
2.) Nozzle could be longer: With the standard lens (50.8mm focal length) the clearing between nozzle and material is about 22.3mm. Still works pretty good with a 60L/min comprossor, but would work even better with less clearing.
Still a "must have" upgrade for the cheap chinese K40 machines ;-)
This is a great price on this! This replaced the original head and air assist nozzle on my DIY laser. I always had problems getting the air assist nozzle aligned correctly. Not only does this provide more clearance between the nozzle and the cutting surface alignment of the nozzle is effortless. I highly recommend this!
