Focus Lens Options

1.5” lens is appropriate for extra fine engravings such as fonts below 6pts.

2.0” lens* has a good combination of fine engraving and thin cutting for fonts between 6pts and 8pts.

2.5” lens is appropriate for cutting up to ¼” of material and engraving detail to around 8pts.

5.0” lens is for cutting thick foam. it is also a good lens for engraving into deep bowls, when more room is needed.

*This is the included lens for Hobby Series Lasers.
