Hello all of you, I hope you can help me out here. I'm doing some spectral experiments at university, and I recorded the attached spectrum of a halogen lamp with an integrated reflector. But there are two additional local maxima in the spectrum, at around 806 and 910 nm. I just can't figure out what the source of these is. I hope I'm at the right place for such answers here. Thanks in advance, Rico
