There are four different lenses for use on the LaserPro MERCURY as follows:
Focal Length
Resolution
Cutting capability
1.5” optional
2.0” standard
2.5” optional
4.0” optional
High
Low
Thin
Thick
The high resolution lens is designed for precision engraving, while the low resolution lens is
mostly applied for cutting due to its lower beam divergence which results in a straighter cut in
thick materials.
The longer the focal length, the bigger the beam spot size. Although it is not ideal for high
resolution image engraving. The large spot size of low resolution lens can spreads the laser’s
heat over a larger area, which helps minimizing melting thus can be applied to engrave certain
kinds of plastics.
