Laser engraving and laser cutting of wood Tips
Generally, 1.5" or 2" lenses are fitting for just about any wood laser engraving. However, for cutting, the material' thickness must be kept in mind. The thicker the material is, the longer the lens' focal length must be. For 1/8" thick wood we recommend you use a 2" lens. For 1/4" thick we recommend a 2.5" lens.
