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...
Hello all,
I am new to the laser. I am in the verge of ordering a laser projector.
Basically an electrical engineer, graduated in 2012.
Currently volunteering for a Non profit organization
Need your inputs on laser beam Vs visibility vs power
