Why Do Infrared Leds Glow Red at George Guerra blog

Why Do Infrared Leds Glow Red. To the camera, those led's are. A red glow is seen as the ir wavelengths sit just past the visible red spectrum of light. So, although most ir wavelengths are. Although humans cannot typically see ir wavelengths, weaker ones may emit a visible red glow. The infrared leds emit a faint red glow, but this is not visible to the human eye, allowing the cameras to remain hidden and inconspicuous. Our eyes are slightly sensitive to the shorter wavelength ir resulting in the red glow. Most ir sensitive cameras don't have a problem with the 940nm leds although some. The net effect of these two things is that when near infrared led's are driven very hard, some photons will come off of them that are visible. The red glow from the ir emitter is noise that can be filtered out using a pass through filter (in your case a 940 nm pass through filter). 940nm ir leds is growing somewhat with the benefit of being 'invisible' / no visible glow but with the downside of roughly half the distance covered for a given. A red glow is seen as the ir wavelengths sit just past the visible red spectrum of light. Among the various hues that illuminate our world, the radiant red glow emitted by infrared lights stands out as both captivating. So, although most ir wavelengths are not detectable by sight, humans can detect ir through its emission of heat.
