The material onthis page is not medical advice and is not to be used Choose for oils that are made by crushing or pressing plants or seeds, rather than through heat or addition of chemicals. Also note that oil is incompatible with dry lenses; using oil inappropriately can distort images. W1/O was formulated with different electrolyte solutions (W1) dispersed in various oils (O) using polyglycerol polyricinoleate as a stabilizer. Place a drop of immersion oil on the cover slip over that area, and very carefully swing the oil immersion lens into place. Swing the high-power objective into place and (continuing to look at the stage from the side), use the coarse and then the fine focus to bring the objective front lens into contact with the oil.

Microscope Activities, 32: Immersion Objectives - McCrone The refractive index of air is approximately 1.0, while the refractive index of glass is approximately 1.5. Taking this difference into account, the purpose of the immersion liquid is to match (as closely as possible) the refractive index of the glass between which the specimen is mounted, therefore, increasing the amount of light rays which will form the final image. Microscope Immersion Oil | Microscopy Today | Cambridge Core In Figure 4 (a), the target image was captured with the oil immersion objective and no water between the test target and cover glass. 2.
