Focal Length of Lens in Laser Beam Machining (LBM) Formulas

Focal Length of Lens is determined when lens is focused at infinity. Lens focal length tells us angle of view and how much of scene will be captured. The longer focal length, a narrower angle of view. And is denoted by f_lens. Focal Length of Lens is usually measured using the Meter for Length. Note that the value of Focal Length of Lens is always positive.
