Glossary of Terms
#2 Mirror – A mirror located at the far left side of the X-Axis Arm (within the #2 mirror cover) used to direct the
horizontal laser beam from the Beam Window into the Focus Carriage.
#3 Mirror – A mirror (part of the focus lens assembly) (1) located in the Focus Carriage used to direct the horizontal
laser beam downward onto the work piece.
Air Assist Cone (Coaxial Air Assist) – An accessory that attaches to the Focus Carriage to direct compressed air vertically
downward, in line with the laser beam, onto the surface of the work piece. On some materials, air assist can be used to
reduce the burning eects of the material from the laser beam’s intense heat. It also can help disperse smoke and gasses
created by processing some materials.
Air Dryer – A refrigerated device or a desiccant moisture trap that reduces the moisture content of air going to the
laser system for air assist. Air assist requires oil-free, clean, dry air with no water droplets. Water on optics can damage
them. The refrigerated dryer uses a Freon cooler to chill the air and remove moisture. The desiccant type uses replaceable
desiccant crystals that must be changed when they become lled with moisture.
Back Sweep – An accessory that attaches to the Focus Carriage to aim a jet of compressed air onto the surface of the
work piece at an adjustable angle. On some materials it can be used to reduce the burning eects of the material from the
laser beam’s intense heat. It also can help disperse smoke and gasses created by processing some materials.
Beam Alignment – A procedure that is performed on the laser system by adjusting the #2 Mirror to produce optimal
laser engraving/cutting.
