100x lens is used with oil immersion
Oil immersion is used to minimize light refraction and increase resolution by eliminating the air gap between the lens and the specimen. The oil has a refractive index close to that of glass, allowing more light to enter the lens and improving the quality of the image.
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
Immersion oil is used in Gram staining to enhance the resolution of the microscopic image. It helps to reduce the refraction of light, resulting in a clearer and sharper image of the bacterial cells. This is particularly useful when observing Gram-stained slides under oil immersion microscopy.
Cedar wood is used with oil immersion objectives in microscopy because it has a refractive index similar to that of the oil (usually 1.515) used to fill the space between the objective lens and the specimen. This minimizes light scattering and improves image quality by increasing numerical aperture and resolving power.
oIO, stands for oil immersion objective. it was discovered during 1870. the OIO, magnifies the actual size of the specimen , 100 times, with the aid of placing a drop of ceddar oil at the top of the coverslip in slide. Remember that the OIO objective must touch the surface of the oil.
Immersion oil typically used in microscopy is a type of mineral oil or synthetic oil with a refractive index that closely matches that of glass. This allows for minimal light refraction and improved image clarity when using high-powered objectives. Commonly, a specific type of immersion oil called cedarwood oil or synthetic immersion oil is used for this purpose.

If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.

Mineral oil can be used as a substitute for immersion oil in some cases, as both provide similar refractive indices that can enhance the clarity of microscopic images. However, immersion oil is specifically formulated for microscopy, offering better optical properties and reducing the risk of damage to the microscope lens. Using mineral oil may not provide the same level of performance and could potentially lead to issues with lens clarity or longevity. It's best to use immersion oil designed for microscopy whenever possible.
Oil immersion objectives are used in microscopes to increase the resolution of the image by reducing the refraction of light as it passes from the glass slide to the objective lens, minimizing distortion and increasing clarity. The higher refractive index of the oil (typically immersion oil with a refractive index of 1.515) helps to capture more light and reduce scattering, resulting in a sharper image. Oil immersion objectives are typically used with high numerical aperture lenses for maximum resolution in microscopy.
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
the hanging drop procedure uses a thicker slide, which could crack if the oil immersion lens is used. My bio professor worte: hanging drop slides asre too thick to use under oil.
Immersion oil is used in Gram staining to enhance the resolution of the microscopic image. It helps to reduce the refraction of light, resulting in a clearer and sharper image of the bacterial cells. This is particularly useful when observing Gram-stained slides under oil immersion microscopy.
Immersion oil is a type of oil used in microscopy to improve resolution and maximize the amount of light collected by the objective lens. It has a high refractive index, usually close to that of glass, which reduces light scattering and allows for clearer image magnification. Immersion oil is typically colorless and odorless to minimize interference with the sample being observed.
Oil immersion objectives are used in microscopy to achieve higher resolution and minimize light refraction. They are designed to work with a special type of immersion oil that has a refractive index close to that of glass, helping to reduce the scattering of light. This results in clearer and more detailed images, particularly at high magnifications.
