چه طول موجی یرای دوربین دید در شب مناسب تراست؟
تصور من این است که 850 بهتر است ، ولی 950 نامرئی تراست.
The two prevalent kinds I see seem to be 950nm and 850nm. For the purposes of making a night vision camera, which one would be more bright? I would think 950nm because it's closer to the visible spectrum, but everyone else seems to say 850nm is brighter. So which one works better? Or should I just buy one of each and see for myself which one is brighter?(as in, it depends on the camera)
Pick the 850nm one. As shown in the following image (from here), it is attenuated less than 950nm.
850 کمتر از 950 لاغر شده
