Fig. 7: The Refractive Index of Immersion Oil

Immersion oil used for microscopy has the same refractive index as glass, meaning it behaves optically as if it was glass. This is a bottle of immersion oil with the dropper filled with air. The air has a refractive index of 1.00 while the oil has a refractive index of 1.52.
