Default Re: line to dot

If you look closely, you can see that the dot is still a square. It might be less of a retardofck line, but it's still not round.

Short of some very expensive mode correction optics, you're not going to be able to get a round beam ( a 'dot') out of them.

Both anamorphic prisms and cylindrical lenses are for fast axis correction. Their effect is to make the fast axis diverge at a similar rate to the slow axis.

A square is about as close as you'll get.

A square a dot just as long as it doesn't diverge as bad now if if only all this could be fit into a handheld
