I am still waiting for my Classic 150 to be repaired/replaced, but I was wondering if anyone could chime in on what they are measuring for beam diameter is at the aperture. Mine was ~1mm. Knowing that beam diameter and divergence are inversely related, I am confused as to how the handful of reviews on this site state a divergence of 1.1 mRad. :huh:
