Default rectangular beam

Gents, I wonder if somebody would advice me.
I need in my application rectangular laser beam shape.
How to achieve that? What makes rectangular one, lens or laser diode type?

Default Re: rectangular beam

Maybe cut something so it has a hole in rectangular shape? That's the quickest way I can think of.. It should not be something that can easily burn if what you are using is a high powered laser.

Default Re: rectangular beam

A shaped aperature will only work if its placed relatively far from the laser.
