20mm Laser Lens FL 50.8mm/ 2" Co2 ZnSe Focus Lens for Laser Engraving Cutting Machine, Laser Engraver/Cutter (FL50.8mm (2inches), Diameter 20mm(0.79inch))

I use it with my Thunder Nova 35 and it works great!

I decided to try adding this lens to my laser and it was a great choice. Cuts cleaner and allows the head to be further away from the material

These laser lenses seem to be of great quality. I've ordered several before of different focal lengths.

Good alternative to the Thunder laser brand lens. I haven't had any issues with the lens in my Nova 51". This is for the 2" nozzle.

This fit our Thunderlaser 35/100 and works like the original.

good one
