Re: Custom $1000 589 laser
Oh thanks buddy, thanks for the info also!
Incredible BBB! What a good job. +rep from me. :beer:
Also, if want to estimate the beam specs such as the divergence then just measure the beam (B dia1&2) at two specific distances (d1&2). It is best to use a vernier to measure the spot. Then use this equation:
(B dia2 [mm] - B dia1 [mm])/(d2 [m] - d1 [m])=Divergence [mRad]
