Well even with a normal lens on these hobby builds we're still getting as low as 1.6 mrad on the fast axis which is actually pretty awesome. The slow axis is as low as .2mrad. Since nova claims it's an elliptical dot they might not even use corrective optics either. I think they're just putting the lens closer to the diode to get the smaller beam diamter than we are which makes the divergence a little worse.
