GCC offers four different focal lenses namely the 1.5”, 2.0”, 2.5”, and 4.0” for different applications. The
number description, 1.5”, 2.0”, 2.5”, and 4.0” signifies the distance of where passed through beam will
converge. For example, when a laser beam passes through a 2.0” focus lens, the beam will converge at a
2.0” distance resulting in a concentration of energy at that spot.
The resulting spot size from the different focus lens are a o different and the following chart shows the
different spot sizes achieved from the different lenses.
1.5” Lens: The 1.5” lens is best when used for engraving of very fine detail

thick acrylic.
4.0” Lens: The 4.0” lens is good for 10mm and above acrylic cutting.
