670nm 6mW 9mm diodes on the bay. "3 For Cheap"

Hey All,

Just a quick One.

Nothing special on these diode but hey its a different WL to add to your Collection. You can still see the beam pretty good with Fog in the room.

Here is the Link:
670 nm 6 mW Laser Diodes NEC P/N: NDL3210 3 pcs | eBay


Found these a little wail ago just final got one out to test. They are Extremely sensitive diodes. A 1mA or less drift and LED. I was able to get 6mW with a Standard acrylic lens at 58mA but LED at 11mW at 70mA.

I have Mine Set to 65mA and is doing 9mW. I want to see how long it will last. Using my Diffraction grating i can tell that these are around the 670nm. Its In between my 660nm and my 685nm lasers but closer to 660nm.


Here is what they look like in the packaging they come in.








Love the Bags for what its worth.

Anyways, Just thought i share.



Keep on Lazing.....

Nice research work again :wave:

+ 1 :beer:


Have to spread some love first :shhh:

I think I might get them too. What size are they, 9 mm or 5.6 mm?
