FTIR imaging question

Hi guys,
Just a quick question. If IR light is unable to travel through an object, such as glass, if I were to image this object in transmission or reflectance, will I just get noise??
Thanks heaps,
Astrid

It depends on your sample holder. But in transmittance, yes, you will only see noise. In reflectance or on an ATR instead of a cell, you may get a spectrum. Unless something absorbs perfectly at all wavelengths, which doesn't seem likely to me. Cf.

Hey, I'm not judging. I just like to shoot straight. I'm a man of science.
