When using a 100x objective lens, it is recommended to set the condenser to its highest position (also known as the "oil immersion" position). This helps increase the resolution and contrast of the image by optimizing the light entering the lens.
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.

Using oil on a 4x objective lens is generally not recommended, as these lenses are designed for air use and not for immersion. Applying oil could lead to improper focusing and image distortion. Additionally, it may damage the lens or the oil could contaminate the microscope. For optimal results, oil immersion techniques should be reserved for higher magnification lenses, typically 100x.
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.
no
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.
No, it is not recommended to store the microscope with the oil immersion lens in position. It can lead to the oil drying out and potentially damaging the lens or affecting the quality of future observations. It is best to clean the lens and remove excess oil after use before storing the microscope.
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.

When using a 100x objective lens, it is recommended to set the condenser to its highest position (also known as the "oil immersion" position). This helps increase the resolution and contrast of the image by optimizing the light entering the lens.
Wet mounts are not attached to the slide, it is "floating". If you use an oil immersion lens, you have to put a drop of oil on the slide cover so the light can correctly focus. The oil will cause the slide cover to stick to the end of your Oil immersion lens. When you focus the field of focus will stay the same since the slip cover is stuck to the lens. When you go to change objectives, the cover will travel with your oil immersion lense.
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.
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.
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.
