Lenses

In order to have a useful laser system, the light from the laser diode needs “modification.” This is where laser lenses come in; we need lenses to direct and focus the light for the different applications we may have. You can get a wide variety of results using the same laser but different lenses, so that you can go from cutting ¼” softwoods or opaque acrylic to engraving a very detailed crest on genuine leather.   

Currently, there are 4 lens types that we offer:

Lens Specification Chart

Lens Type: 3 Element  G2 G7 G8
Efficiency: 70% 95% 88% 90%
Tested Focal Length*: 63-67 mm 28-35 mm 83-85 mm 70-75 mm

*Focal Length is Measured from bottom of laser assembly aluminum heatsink to the material laser is used on 

3-Element lens

  • Best for engraving 
  • Smallest beam size → perfect for detailed engraving
  • Lowest power output → may not cut as well as other lenses
  • Medium focal length 

G2 lens

  • Best for cutting 
  • Largest beam size → perfect for bulk material cutting
  • Highest power output → can cut through material with less passes
  • Smallest focal length → can cut thicker material due to low Z-axis travel constraint

G7 lens (Balanced Multi-Purpose Perfection)

  • Good for basic cutting and engraving
  • Medium beam size
  • Good power output
  • Largest focal length → can cut/engrave thicker material than G8 lens

G8 lens (Balanced Multi-Purpose Perfection)

  • Good for basic cutting and engraving
  • Medium beam size
  • Good power output
  • Medium focal length
