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.
One thing that can happen if you use the coarse adjustment while the oil immersion objective is in place is that the slide will end up breaking. It is better to use the fine adjustment.
To clean a low power objective with oil on it, use a lens tissue or cotton swab lightly moistened with optical cleaning solution or alcohol. Gently wipe the surface in a circular motion to remove the oil, being careful not to scratch the lens. Finish by drying the lens with a clean, dry cloth.
When viewing a slide under oil immersion, it is best to use the 100x objective lens. This high-power lens allows for greater magnification and resolution, making it ideal for observing fine details in the specimen. The use of immersion oil helps to reduce refraction of light and improves image clarity by providing a medium with a similar refractive index to glass.
A magnification of 100x typically requires the use of a 100x objective lens on a microscope. Different microscopes may have varying objective lens magnifications, but for a total magnification of 100x, the 100x objective is commonly used.

The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.

To achieve a total magnification of 100x, you would use a 10x ocular lens (eyepiece) with a 10x objective lens. The total magnification is calculated by multiplying the magnification of the ocular lens (10x) by the magnification of the objective lens (10x).
So you do not crack the high power objective lens - this lens is very fragile and expensive.

Leaving immersion oil on the objective can attract dust and debris, which can impact imaging quality and potentially damage the lens. In addition, it can cause the oil to harden and become difficult to remove, leading to maintenance issues. Cleaning the oil off after use ensures optimal performance and prolongs the lifespan of the objective.
Cleaning the oil immersion objective immediately after use is important to prevent dried oil residue from accumulating and affecting image quality. It also helps to maintain the lens in good condition and prevent contamination between samples. Delaying cleaning can make it more difficult to remove the dried oil and may lead to damage or reduced performance of the objective.
Refracting telescopes use a main lens made from glass and called the objective lens.
The high power lens of a microscope is used to magnify the image of the specimen to show details that are not visible with lower magnification. It is typically used to observe finer structures and smaller details of the specimen.
When using a 100X objective lens, you typically want to use a high numerical aperture (NA) condenser lens to match the high NA of the objective lens. A condenser with a NA value equal to or greater than the NA of the objective lens (typically around 1.4) is recommended for optimal resolution and contrast in microscopy.
