Hi all,
Just to clarify a point re:
"mRad is milliradius and that shows you divergence. The lower the number, the less the beam spreads in distance. Usually, you'll get <1.2mRad."
mRad actually stands for milli-Radian (1/1000 of a Radian). Radian is a unit of angular measure like degree is.
1 Radian. = 57.296 degrees
1 mRad = 0.057296 degrees = 206.26 arc secs.
Rgds,
