If you look closely at the 100x objective lens on a
light microscope, you will usually find the word "OIL" written on the lens. This inscription means that the microscope lens is an immersion oil objective lens and the best results will be obtained using immersion oil.

| Immersion Oil Microscope Lens |
![Frogs blood no immersion oil 1000x]( "Frogs blood under microscope using no immersion oil") |
| Frogs blood, 1000x magnification, no immersion oil used. |
![immersion oil 1000x frogs blood]( "Frogs blood 1000x with immersion oil") |
| Frogs blood, 1000x magnification, using immersion oil. |
Notice the difference in clarity between the two images that were captured at 1000x magnification. Once you have finished using the microscope with the immersion oil. Be sure to
clean off the objective lens so the immersion oil does not harden on it.
