Refraction in microbiology

WebPlacing a drop of immersion oil, which has a refractive index similar to glass, between the slide and the objective lens decreases this refraction, and increases the amount of light passing from the specimen into the objective lens. This results in greater resolution and a clearer image. Figure 3.9. Refraction of light at 100X .
