I've been thinking of trying this for a few days so I want to see what you all think. The 445nm diode has different diverging coefficients for the two axis so couldn't you use anamorphic prisms to adjust the divergence of only one axis to match the second to get a round beam? This would be too hard to implement into a portable host but it'll be perfect for labbys, and especially for those of you who want to use 445nm in your scanners.
First look at this link:
Olympus FluoView Resource Center: Diode Lasers - Interactive Java Tutorial
See what I mean now?
Those anamorphic prisms can be salvaged form a B&W Tek BWB-10-OEM 10mW 473nm Labby. I know there in there because I have one.
See:
There are non-functioning units available on eBay for about 40 bucks. You'll get the lenses, a potentially nice labby host, a 2w 808nm diode (assuming it works), and a couple of TECs among other things. Seems like a good deal to me. Furthermore, since the laser is 473nm the lenses are surly AR coated for that range, they should be good for 445nm too.

Just a thought ...what do you think?
