The Focal Spot Size Calculator
There are matrix methods that can be used for propagating the diameter and curvature of the beam, but if your main interest is simply the location of the new focus (i.e. beam waist) or the size of the focal spot, you can use the Focal Spot Size Calculator tool on the Ophir website. Dr. Ivker Our expert – will explain you how
