Bigger 20mm Input Beam Focal Length 420mm Scan Area 300*300  USA  ZnSe CO2 Galvo F-theta Scan Lens  Laser Marking Machine Lens

This is not standard size of f-theta lens, this f theta scan lens diameter is 70mm,it is specially for fine marking, with bigger input beam, the focus spot is much smaller than normal size.

the spot size can reach 0.2mm, the standerd size spot is about 0.4mm

This zise f theta lens is specially good for DIY a marking laser machine or enhance your laser machine ability, if you buy from a manufacture with input beam 20mm lens, the laser machine price would be $10000 higher than the standerd size.

The connection thread is still M85*1, you can easily upgrade your machine.
