I would like to know how much power an incandescent lamp (say 150W) emits in 1260-1360nm range.
If there is more suitable easily accessible source of light for this range, I am interested to know too.
I don't necessarily need to know the exact figure, I need to know how it compares with 7dbm (much more than that, much less), etc.
From some arbitrary sources on Internet  it appears the lamp emits mostly in 500-2500nm range, which is 2000nm wide. My target range is 100nm. Ignoring it is non-uniform, and perhaps some finer details I should have remembered from my university optics courses, I gather some 1/20th of original power will appear in 1260-1360nm range, for 150W lamp it is 7.5W. Which seems to be some 3 orders of magnitude more than 5mW ().
I appreciate it if someone with good knowledge of optics can tell if this makes sense, and offer same explanations in a language appropriate for optics domain.
Also, I'm comparing directional laser diode light source with omni-directional lamp. I'll post another question for that.
