The importance of focal positions in laser cutting

Jan 08, 2010· Now, if we substitute a 5-in. (127-mm) lens, using the same 20-mm raw beam, the diameter at the focal waist would be 170 microns (0.170 mm). Concurrently, a change in the depth of focus between the two lenses would occur. The 3.75-in. lens would have a DOF of approximately 1.2 mm, compared to a DOF of 2.16 mm for the 5-in. lens (see Figure 4).
