Many thanks Swami
yes, I've invested tons of hours, money and effort on developing. I'll post on "Selling" here on PL soon. fingers crossed!

great! and i'm sure we'd all like to see the farfield

Oh!! ok, ok. Your builds are fantastic Chris, congrats.
Why you go along with 4mm instead Dave's F2 colis? easier stacking? better LD centering?
thanks!

We used 4mm collimators on that build.

Also, we have a little divergence to play with on that axis as it is still slower than the fast axis after expansion.

Thanks.

2 primary reasons we chose the 4mm..... We had a budget to work with, so price was a big deal. Second, when I measured the beam at aperture with the china G2 I must have made a mistake. I thought the beam was a little smaller than it turned out to be. I knew the beam would be a little big. I thought the losses would be acceptable with the 4mm. oops!

Oh, and I was also trying to match with the B and G

looking back.... the 2mm would have been a better choice

I'm still thinking going with G2 for red +prisms is a brilliant idea.
I've noticed china G2 sometimes comes with not very well centered lens inside...so beam out is very angled and uncentered from LD housing (asymetric wings and so on)
However no problems with DTR's G2... perhaps bad luck with my samples

sure! Nice beam profile once again spatials will be adjusted. I'll take some pics. 0.92 mrad each module.
