because the oil have a refractive index near the glass one so we can work at high power without lossing any details by eliminating the air gap between the the specimen and the objective lens >>>> a.sh (iug)
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.
scanning objective
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000
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.
In light microscopy, oil immersion is a technique used to increase the resolution of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens.

The oil immersion lens @100x
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.
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.
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 lens with the greatest (positive) curvature. The lens with the highest diopter.
The oil immersion objective in a microscope is used to gather more light from the specimen and increase resolution. By using oil with similar optical properties as glass, the objective lens can capture more detail and produce sharp images of the specimen.
The oil immersion objective lens provides the highest magnification in a compound light microscope, typically ranging from 90x to 100x. This lens requires a drop of oil to be placed on the slide to reduce light refraction and increase image clarity and magnification.
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.
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.
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.
