Immersion oils are essential for routine laboratory work, especially in hematology, cytology and microbiology. They are commonly used for high scale magnifications in order to secure high resolution and a clear image. There are several types of immersion oils that differ according to viscosity and certain properties required by different microscopy techniques. They all have a common refractive index of 1.5150, equal to the refractive index of glass.
