Default red laser oval spot fixing optic....

I'm soon going to be building a 10mw 635 laser, but I'm really not liking the large oval dots of the direct injection laser diodes. I've read on hear a few times about an optic that will correct the oval dot down to a nice round dot like a DPSS laser.

Does anyone know what this device is called, and where I could get one?

Any help would be greatly appreciated!

I believe you'll need a pair of anamorphic prisms. They are usually pretty pricey. However, I think Laser Ben was selling some Melles Griot modules with a pair of anamorphic prisms for $30-50, IIRC. I'm pretty sure that he sold them all, though.
