What is the IR wavelength (nM)? Is it over 800nM?

Not sure off hand. The IR light is visible to humans though, if that is what you are referring to. You do have to be in front of the light in order to see it. The estimated range of 80 yards for the IR is pretty accurate. Much farther if a reflective object. One thing about this scope that isn't mentioned anywhere is that after powering up the scope and the view is green you can turn it off and still have the same night vision. I have even taken the batteries out and it still works!

IR is line of sight. If you can't see the sensor it won't work. That goes for any IR receiver. You would need RF (radio frequency).

I have my camera set up where the person has to walk within 8 feet of the camera and those are recognizable. As for the infrared, I don't know.

Yes, the IR LEDs emit a visible red glow in the 890 nanometer wavelength.it is a very good illuminator for the price. I have also purchased Invisible IR-200-940 CMVision 940nm Wavelength 198 IRLED.Look for 940nm IR LEDs. If u want invisable. But be careful. Alot of cameras will not detect light at that high of a wavelength.

The wavelength is close to 380-390 nano meters Think the speed of light as if in a rainbow I like your interest.

True, Sharon, the IR unit is mostly metal and quite heavy on account of that. Make no mistake, however, it is imported from China nonetheless!

I'm not sure that I can help you, since I don't know the difference between near and far infrared. What I can tell you is this, I use GE Chill Chaser bulbs. Their code number is 250R40/10. The package advises that the bulb be no closer than 18 inches to your skin. I use the heat lamp for treating back aches and arthritis. It seems to work well in that role. I use it at about that 18 inch range and it is helpful that it has both a timer and a rheostat to control the intensity. Hope this was helpful.

I no longer have the unit, I had to return it because it produces light at the wrong wavelength for my cameras. In other words there was no illumination at all. I'm looking for IR lights that produce light at 830 to 850 nm (nanometers). As for dimensions, I think it was about 6" by 4", but don't quote me on that. Good luck.

As far as I can remember, my B-Cure emits a fixed wavelength of 808 nm. It seems to work well. Other laser companies say a combination of 660 and 905 nm can address deeper tissues. It's hard to know what works best.The green LED contact light periodically fails on mine (it's "on" this week), but, the red glow of the actual laser is still fine (visible in a dark room) - after 15 months of use (twice daily at 35 minutes per session) on my right knee.-Brian

This is an older model of the D70. There is no mention of infrared in the manual.

Right and I believe that what he meant by that is that radio frequency is the far red area of the EM light spectrum. (600-800 nm) Radio freqency is often refered to as red and/or far red.

Other websites show this as a 390nm wavelength but the ultra fire website doesn't show this model.

IR is visible. viewing is green. I have used at 100 yds but it may work at a longer range. I was able to see a rabbit fairly clear at that range.

Hello, I bought a light source that looks exactly like the one pictured here. So, it is probably what you are researching. I have been told that my cameras need 820 to 850 nm, but when I hooked up the ir light, there was no illumination at night. If I turned the light directly to the camera about 8 feet away, the front panel of the light was white, but it didn't illuminate anything when turned away, I mean nothing. What a dissapointment. I don't know what else I can try. The ring of ir lights that are inside the glass dome around my cameras are useless, if I turn on those lights, the glare from the glass dome is way to bright to see much of anything.Good luck, Dan Hello, I bought a light source that looks exactly like the one pictured here.
