making a spatial filter would probably solve your beam halo / spill problems. i would go for that over using prisms on single mode diodes.

However now I *do* have a bench power supply on the way as I've just found out the max voltage for the PL450B may be 7v and the X-boost 7v but the supply max is actually 4.5v
need to be more careful. The others are 7v on the 520nm and 12v on the 638nm for anyone else who couldn't find that info on the bundle's page.
The beam correction stuff is being picky to make it more fun. I used to do a lot of graphic design stuff professionally, I notice all the spill and halos and different size beams so I'll appreciate it in my home projector even if noone else does
Not planning on TEC at all, I didn't order those drivers they just upgraded them from the lower spec ones to make up for causing me a bit of a panic with their email going down.
I wondered about the DZ board.... I'll hang onto it for now.
Cheers! More pics once i get some bits fixed together
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
