Very nice.
I've been thinking about getting one of the green arrays, but they are rather expensive, still the divergence of each beam should be much better than the blues and I've had some success with concave-convex lens pairs with the blue beam bundles, should be even better with this green array.
Do you have any pics of the output/beam bundle over any distance ?
p.s. Here's a couple pics of some lens testing with a blue array, you could possibly build a stationary convex and zoom to focus concave lens arrangement into your green array pistol, something I've wanted to do but haven't yet.
