…sensor for beam size measurement, a good rule of thumb in the case of round beams is that the beam diameter should be 15 to 20% smaller than the physical size of the array or sensor. In the case of beams that are not round, use the longest dimension for this comparison. In Depth: Laser Beam Size The…
