hey hey, I recently scored this super old laser pointer on ebay and I kinda want to show it off. It's super clunky and 670nm is very deep and nice to look at. i have a picture comparing it to 632.8, 650 and then 670 on the right. The camera makes it look more pink but in person its just very deep compared to the other two. it also uses a 9mm diode too which I thought was kinda neat.
