Nice pen build!!. what is that gold pen? i think laser66 24K gold pen build
Thanks Rich it was hard to see it go but it was a quick build as a gift for a friend who also appreciates lasers. I believe the diode was a sharp 505 nm that I bought on eBay. It never ran hot even after a few minutes of it being on. Love the mint color, I do miss it so much I might buy another diode and give it another go. I don't have the black piece of plastic I used to isolate the diode from the host, I don't even remember where I got it but it was a perfect fit to hold the diode tight in place even with a hard spring that I ended up replacing as to not have it fall apart on my friendHi, Nice build for a lower power single mode diode like the PL520 , short cycles , good job..
Yeah I did that after posting the last picture. Here it is with the ring on itYou should put a ring on the lens housing. It helps when you are trying to focus the beam. These are normally set to 1.8 amps, so 240 mA would be quite low. Considering you put it into a pen, that is probably just as well.
