I would like to know how divergence is calculated, what units are used on its measurement and what divergence values are acceptable for a normal laser.
Thanks!
Thanks!

TEORICALLY....every focusable laser could be at 00000 mrad... is it true? you could tell me" yes.... but i'ts a VERY DIFFICULT thing to do.. because changing 0.01 millimeters the rotatory adjustament.. the mrad could change A LOT".
i think..... if a laser is focused when is construpted.... could be focused at 0000 mrad......
another questiondemand... oh i don't know how i must say in the english languade qhen i want to ask somewhat...QUESTION..DEMAND. or REQUEST ?
a laser focused at near 00000 mrad... could reach a quite infinite distance? for eample.. a 100mw green laser at 00 mrad.. could reaches about 100 kilometres? maybe not.. because the light is absorbed by the Particle pollution.. but a 250 or higher power... should reach more of 100 kilometres...
i want a 0 mrad laser :
--Hallucynogenyc-- said:I've been trying to measure the divergence on mine and i obtained 0.6mrad for a newwish laser. Is it posible or just me who is not making the good measurementes.
How to do them properly? I tested on 10 meters and found it was going from 1.5 at first to 7.5 at end, maybe I should use a longer distance?
