High power IR flashlights are popular with nighttime hunters. Yes, you can indeed see in the dark with a powerful IR flashlight and a camera that is sensitive to IR. Either a black & white camera or a color camera with it’s IR filter removed. In color cameras, IR alters colors and focus so its necessity to block much of the IR with an IR cut filter in order to get a good color image.

850nm IR leds will give the most light / brightest image on a camera. But 850nm has a slight red visible glow to human eyes. 940nm IR leds are invisible to human eyes but cameras are less sensitive to it / less brightness on camera. IR leds on ebay For the best IR leds you need to get osram oslon or led-engin IR leds.

Anyone knows where to buy a BLF (read budget) style night vision headset ? 

Budget but we'll working.. I've always been interested in that stuff!

Hi

I’m currently building a DIY night vision Goggles.
My main “inggredients” are this dashboard camera (http://www.gearbest.com/car-dvr/pp_3704.html) and Google Cardboard (http://www.gearbest.com/action-toys/pp_70013.html).

As additional IR light source, I build a custom IR flashlight and attached to it.

Is there any aftermarket IR visible googles/glasses?

any sony 0lux camcorder ses IR, i still keep mine 8mm tape one, even thou it is very outdated, but sony does not make consumer grade 0lux cams anymore, so it is either 5k and up pro cam, or old tape cam.

i also build 10w 850nm for it, it really turns night into day.

LED you could buy here http://www.aliexpress.com/store/product/1W-940nm-Infrared-LED-High-power-LED-1chip/330416_1604709804.html , 7135 type (or may be any type of step down driver with current regulation) driver should work with it.
I had put similar led (“3W”) to p60 drop in with 7135 (~1Amp total) it works well.

I don’t need the built in IR light either, not sure if there is such thing that with only the glass/filter itself at much lower price.

$3 How is that for budget? Google Cardboard with Head Mount No, I’m actually serious. Add some foam to seal it nicely around your face (hardware store thick “open cell” / soft weather stripping). Not only for comfort but to keep light from leaking out. Just need a IR flashight. I’d go for an custom oslon black led light mounted right to the goggles. Paint the cardboard black, to look less like cardboard and for water resistance.
If you want the best performance you need to remove the camera’s IR filter.

Cool. But if I’m using my phone is there any way to remove the IR filter of my phone camera?

hey for what need you that nightvision ?

pest control,animal spotting by night , or so ?

greets

I’m big into UAVs and drones and love flying at night so I’ve got quite a bit of expeirence with Night/Low light setups. There good enough to pilot a drone through at high speeds with nothing more than moonlight. I’ve never had to use a IR illuminator with any of these setups and really arent needed unless you are going to a location that has absolutely no light like deep into a cave…

I definatly would recommend these following cameras.

Sony Mini Cam
Sony Board Cam
Super Low Light Camera

And throw one of these lenses on there to really boost performance.
Light Collector

Another thing to consider is the latency of the camera alot have a fairly high lag and depending on your purpose you don’t want that. The sony’s are all damn near real time.

I’m at work right now and cant link any videos but when I get home I’ll dig one up so you can see how these perform and if they will meet your needs.

for pestcontrol rats,night predaters can you use one led red 720 nm

it is far red and if you it use on 0.7w its perfekt.

infrared720nm =red/beginning infrared and full infrared 850nm or higher

you can drive it easely 1,5 w but 0.7 is betther for night annimals you see the eyes more than 50 meter you need no nightvision
