What is the easiest way for you to show me what I need to know to use it?
In the first two boxes at the top you'll need to input two numbers. Those numbers are the size of the beam and the divergence of the beam from the diode minus any optics. The diameter of the beam is very small so a number such as 0.01 or 0.001 can be input into the first box. This only matters if you are making an optical system for a raw diode. For a laser with an optical system measure the width of the beam and estimate the divergence of the beam. the reason being is the expander will be placed well within the Rayleigh Length. within that length the beam only expands 1.4 time it's original diameter or 1.4 times.What is the easiest way for you to show me what I need to know to use it?
