# IR transparent fluids

1. Mar 28, 2012

Hi.
I am working on visualization of flow with thermal infrared camera. As it is known, water is not transparent for IR spectrum of light, so you cant watch phenomena that are occuring "inside". You can only see things that are occuring on the interface of water and wall.

I have been working with some fluids like acetone or dichloromethane, which are transparent only few millimeters.
Now I am trying to find liquids that are transparent more than that, lets say few cm.
So, has anybody been working with such a fluid or does anybody know for a research/article, which has dealed with this things?

Thx.

Hi,

I am also looking for room temperature IR transparent fluids. Were you able to narrow down any fluids with such property ? Please suggest.

Thank you !

Carbon tetrachloride has no IR spectrum.
