Why cedar oil is used in microscope?
Oil of cedar wood was routinely used for immersion microscopy for many years (and is still available today). Despite having a refractive index of 1.516, this oil can turn yellow with age and could damage the objective front lens if not removed immediately after use.Click to see full answer.

In this way, why cedar wood oil is used in microscope? Cedar Wood Oil If not correctly cleaned up after use, it can penetrate and damage the cement which holds the objective front lens in place. Cedar wood oil can also ‘yellow’ with age and has a tendency to absorb light in the ultraviolet and blue range of the spectrum.One may also ask, can we use any oil for the microscope? Oil immersion lenses are used only with oil, and oil can’t be used with dry lenses, such as your 400x lens. Lenses of high magnification must be brought very close to the specimen to focus and the focal plane is very shallow, so focusing can be difficult. Correspondingly, why do we use oil for 100x objective lens? However, once you use the 100x objective lens, the light refraction when using a dry lens is noticeable. By placing a substance such as immersion oil with a refractive index equal to that of the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed.Why is immersion oil used with the 100x objective quizlet?*air has a lower refractive index than glass, light waves have a tendency to bend and scatter as they pass through the air from the glass slide of the objective lens.
