G2 short focal lens.
An efficient lens for 405-445 nm diode lasers.
Optimal for laser cutting and accurate laser engraving.
Has the smaller laser beam spot.
Focal range: 5-30 mm (1/6'' - 1.2'')
Optimal parameters:
Focal range 10.5 mm (2/5″) [range from the lens to a surface]
Focal beam spot 0.134 х 0.052 mm
Optical transmission for 445 nm wavelength = 94%
Comparing laser cutting 3 element lens + air nozzle ver 1.0 vs. G2 lens + air nozzle ver 2.0
G2 laser lens with an air nozzle ver 2.0 (plywood cutting)
Allows getting the thinnest engraving line.
