50(7)nm Chrome Pen

My inspiration to build this pen came when I came across RA_pierce’s 505 Chrome pen build. I just had to have one, too:D

I bought the Sharp GH05030C2LM 35mW diode on techhood for around $16. Had to try it.

After reading all of Paul’s write-ups and testing on these, I asked him about this one I bought and he recommended the Blitz Linear to be best paired with it because they’d both be case positive. He also offered to set it up and measure the WL. I sent him everything and he put the diode into a module paired with a 520 2EG lens I purchased from DTR, and set the driver to 180mA.

Thanks again Paul for setting it and testing and all the helpful tips!! You made this by far the simplest build:beer:

These pics don’t do the beam much justice (iPhone) but here she is.
