Optical coupling oil?.

In Scintillators an optical oil is used to couple the Sodium Iodide Crystal to the Photomultiplier tube. In Microscopes there are oil emmersion objectives. So....are there any oils with the refractive index of air that would be transparent in the light ranges used in astronomical work with CCD's & CMOS quickcams/web cams?.

Coupling in this manner should result in brighter images and a truer contrast. -Larry
