There are some new 685nm diodes on eBay
and the price is pretty good, so I thought I'd
try one out, and the whole deal has been
fairly impressive.
New HLD685035K5J 685nm 35mw Red single transverse mode laser diode medical laser | eBay
This was the first diode I bought on eBay
from China that was actually properly
packaged. It came wrapped in a mylar ESD
bag and even in a diode tray!
There are no specs published anywhere on
these that I could find. They seem to hit
35mW at about 58mA. The beam
characteristics are the best I have ever
seen. The dot is nearly a perfect circle.
I highly recommend picking up one of these
while they are still around. At this price it's
hard to go wrong.
Pinout
Slightly defocused dot at about 20'
The camera is slightly confused by this nearly
IR W/L. To my eye it looks like a deep almost
purplish red.
