Immersion oil is only required when using a light manuscript at 1000 times magnification (10x from occular lens and 100x from objective lens). At 1000x magnification the image will have poor resolution (loook fuzzy) without the use of immersion oil. This is because the cover slip on the sample and air have different refractory indexes. The light scatter that occurs during the transition from glass to air is noticable at such a high magnification. Immersion oil has a refractive index very similar to the cover slip, thus reducing the light scatter as the light passes from the sample to the objective lens.
Not only does oil immersion increase the microscopic resolution of a specimen, it is also transparent. This allows for optimal microscopy views.
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.

Immersion oil has a similar refractive index to glass, which helps reduce light refraction and increase resolution when viewing specimens under high magnification. By increasing the numerical aperture of the objective lens, immersion oil allows more light to be captured and produces a clearer image with improved contrast and detail.
The best objective lens for showing the most detail in a thread is typically the 100x oil immersion lens. This lens provides the highest magnification and resolution, allowing for the observation of fine details and structures in the thread. By using immersion oil, it reduces light refraction and improves clarity, making it ideal for detailed microscopic examinations.
Not only does oil immersion increase the microscopic resolution of a specimen, it is also transparent. This allows for optimal microscopy views.
Before rotating the oil immersion lens into place, make sure that the specimen is in focus using a lower magnification objective. Ensure that the area you wish to observe is centered in the field of view and add a small drop of immersion oil to the slide.
The field of view of the oil immersion 100x lens would be 0.4 mm. This is because the field of view decreases as the magnification increases.
No, it is not recommended to store the microscope with the oil immersion lens in position over the stage. This could lead to accidental damage to the lens or misalignment of the microscope components. It's best to remove the oil immersion lens and store it properly to maintain its integrity and performance.
Because that lens (it does not HAVE to be a 100x lens - other lens magnifications are also available in oil immersion constructions) is made to be in contact with a drop of special oil which covers the specimen. The oil has the same index of refraction as the front lens glass and that way a different optical construction can be used.
False. When using the oil immersion lens, you should first bring the lens close to the slide without touching it, then apply a small drop of immersion oil directly onto the slide. After that, you should carefully raise the lens into the oil droplet to ensure proper immersion and optimal resolution.
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.
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.

The oil immersion lens @100x
A high-quality microscope objective lens with a specialized coating is typically used for oil immersion microscopy. The lens is designed to work with a specific type of oil (usually immersion oil) to enhance resolution and numerical aperture by reducing light loss due to refraction. Oil immersion microscopy is commonly used for high-magnification studies requiring precise imaging, such as in medical or biological research.
