If I remember correctly, the NDG7475 1W 520nm laser diode has about 3 mRad divergence when using a 6mm diameter G2 lens, does anyone have solid figures?

I found a post from someone two years ago who had a newly released NDG7475 and he was getting 2.7 mRad with a bit less than a 1mm wide beam diameter using a 4.6 FL aspheric lens. That seems to be a very low amount of divergence for a 1mm wide beam, I expected that amount of divergence with a 3 to 4mm beam diameter. I wonder if he was measuring correctly? Still looking for divergence figures.
