Brand new, just got it, but decided I would like something else. The verified output of this laser according to Opto is 47mW, not a bad overspec for a 40mW
This pen is no longer for sale. Both green pointer pens I bought from Optotronics had their diodes become loose, and need to be jostled around a bit before the beam gets realigned to shine through the aperture correctly. Not sure if they're way more sensitive than I thought, or what, but it's not available for sale anymore.
That being said if anyone has a more robustly built green laser around 50mW for sale that I could replace it with, please shoot me a PM
