Using immersion oil ... When to use an oil immersion lens ... To use an oil immersion lens, first focus on the area of specimen to be observed with the high dry (400x) lens. Place a drop of immersion oil on the cover slip over that area, and very carefully swing the oil immersion lens into place.

The most powerful lens of the light microscope is the 100x oil immersion objective. Because light is refracted every time it passes through a medium with a different refractive index, (air to glass or vice versa) the quality of the image is reduced with each passage.

Typical immersion oils have a refractive index of 1.51 and a dispersion similar to that of glass coverslips. Light rays passing through the specimen encounter a homogeneous medium between the coverslip and immersion oil and are not refracted as they enter the lens, but only as they ...

(RMS, June,1964, pp.120). Finally, by August of 1877, Zeiss produced Abbe's oil immersion objectives, which became known as "homogeneous" immersion (Innovation, No.1, 1996). Mayall says the date was 1878. However, a bit latter in 1879, Abbe published his paper on Methods for Improving Spherical Correction in the...
