780nm/808nm/980nm Testing!

[Fiddy]

Good hello,

So im intrigued by NIR and IR light, with the regards to night vision and random exploding balloon

So i have acquired the following range of diodes for testing with my night vision equipment.

All these tests have been run off my trusty CC lab style power supply.
The choosen ones for hosting will be run of these Drivers

780nm ?mW 5.6mm (from CD Player)
780nm 250mW 5.6mm
808nm 1000mW 9mm
808nm 500mW 5.6mm
980nm 500mW 9mm
980nm 300mW 5.6mm


780nm

780nm ?mW 5.6mm (from CD Player)

The 780nm from the CD Player works pretty well, this video was from when it was on 100mA which is pushing the limit it i believe.

780nm 250mW 5.6mm
haven't received this diode yet.

808nm

808nm 1000mW 9mm

So i acquired some MOD9 modules from RHD to press this 9mm diode into.
The fitment was amazing, the tolerances combined with the softer aluminum make it a breeze to press in.

Wound the current up to 500mA and away she went, showed up very well on my night vision goggles.

The divergence from this diode is pretty bad, i would say a little bit worse than the 445nm diodes.

The light output is ridiculously bright under night vision equipment and i wasn't even at 50% of the claimed operating current of 1400mA.

Definitely a laser not to fuck with, it will rape your vision quite easily!

808nm 500mW 5.6mm
haven't received this diode yet, hopefully it has a better divergence than its 9mm big brother.


980nm



980nm 500mW 9mm

haven't received this diode yet.

980nm 300mW 5.6mm

Tested this one today, ive never played with a 980nm laser before so i was fairly interested in the results, i wound it up to a lil passed its threshold current and nothing, no light would show up on my night vision goggles.

So then i grabbed my digital camera, turned it onto video, enclosed it in a box with the laser and wound the current up to 400mA. This yielded no light either, so i began to think the diode may be buggered.

Last thing i tried was my trusty nokia mobile phone camera, and bam i could see the beam through the camera.

I will update these, when the other diodes come in.

Thanks for looking! :beer:

Very intriguing, I have yet to pick up some IR diodes myself. 980nm does not pick up on your night vision goggles because the peak operating wavelength of most night vision goggles is 800-900nm.

heres 2 videos of it in action!

Can only get it to 200mW output with the current driver(s)

not bad tho, the beam is like a 445nm with a aixiz 3 element lens.

Awesome IR's. I want to start doing some IR builds. 808nm diodes seems pretty cheap depending on where you get them, so I will start with a 808 or a 780 soon. I just ordered a 300mW 808nm diode so I can fix my friends broken 100mW 532nm laser

Fiddy can you please reupload pictures to imgur, all these crappy unpopular obscure hosting services are lacking revenue to survive, i would really like to see the results of the testing how each shows up on NVG's as well as regular camera with IR filter removed. Particularly curious whether 980nm could be visible for regular IR cameras that have no IR filter, possible application, replacing near IR that glow deep red to ones the eye can't see glowing.

Check the date on this thread... it was last posted to in 2011. The OP hasn't even been logged in since last year. Bringing back old threads is frowned upon unless you have some information to add.

Also, photobucket wasn't obscure at all, that's part of the problem with their new "Pay is $400 a year for third party hosting!" thing. So many people/sites/forums have used their hosting over the years and now (as you can see) those images are no longer working.
