I just looked it up and I'm pretty sure the optical lens is universal with all thor lasers. Correct me if I'm wrong, but I think that's the case. Pretty cool!That lens would fit my Thor H2. Cannot say anything about the Thor M2. My guess is they likely take the same lens housings.
Could be. You'd know more about it than I would. At least for the "2" models I assume, because I searched a bit and also on LPS there is only one option for Thor lenses.That would be a likely assumption. I just can't say it is absolutely correct as I have nothing to back it up with.
