I have compared the beam diameters of two high range lasers(see pic)
Assuming zero lumen drop , see the lux levels at different distances.
Clearly , the LD - low divergence of .5 mrad is having twice the range .
This exercise was an attempt to find our the visibility of white beam.
Assuming the factors such as light pollution, environmental factors are all considered to be favourable to have long visibility.
I m new to the forum..Please need your help
