7 - Choosing the Best Lens
●The name “Flexx” indicates that the machine has two lasers: a 120 watt CO2
laser, and a 50 watt Fiber laser
○ The CO2laser is well suited for engraving and cutting plastics and organic
materials. The Fiber laser is well suited for engraving metals and for
marking metals and plastics.
●The NJIT Makerspace has five lenses available for the Speedy 400 laser, each
with a different focal length.
○ There are 3 configurations (shown as “Component Stacks”) for the lenses
on the Speedy 400. The components that make up each stack include the
lens and the beam expander(s).
●Be sure to change your lens in the Job Control! It is located in the top
left corner where you’ll also be able to adjust Material and Material Thickness
