7.3.2 Fiber Laser Focus Lens

GCC offers two different focal lenses namely the 2.0" and 4.0" for different applications. The number
description, 2.0" 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 also different and the following chart shows the
different spot sizes achieved from the different lenses.
2.0" Lens: The 2.0" fiber laser focus lens with concentrated power within small spot area which
is good at cutting thin metal like 0.1mm copper foil.
