F-theta is the used for laser modules. High energy uniformity lens, narrow focus spot and low attenuation.
How plasma works can get a little complicated. So, I’m explain as simply and quickly as possible. Plasma cutters basically heat up gas so much that it gets hot enough to melt metal. Then, when the metal is heated up enough to melt, it is blown away with gas to make the cut. There’s a complicated science behind this, but I’ll save that for another day! (or you can research on your own if you like).
