nubm31 focalization - metalmatters.co
I am trying to obtain a laser able to burn small plants (or very small plants) at a distance of about 0.75M . will be a scanning device to kill weeds. I found the nubm31 could be interesting but unsure if it can focus enough. I am expecting a dot 1x1mm or at least 2x6mm at 0.75M distance. Looks like nobody did try to focus at this distance.
