Talk:Path Length Matching
I am not sure why you had the first measurements of the red and blue beams at 4 instead of 4.5 thus indicating different path lengths compared to green. I matched them to the diagram (4.5) and all paths are the same length again. Thanks for taking the time to review it though.
It did not really bother me as in the real world sometimes you have to accept a beam placement that will fit on the table and not really the best beam. Thanks for the work!
