The field of view becomes narrower.
The lens used to locate a specimen on a microscope is typically the lowest magnification lens, known as the scanning lens or low power objective. This lens provides a wide field of view, making it easier to find and center the specimen before switching to higher magnification lenses for detailed viewing.
When you change the objective on a microscope from 10x to 50x, the magnification power increases, allowing you to see the specimen in greater detail at a higher resolution. This means that you can observe smaller details, but the field of view will be reduced. Additionally, the depth of field will also decrease, making it harder to maintain focus on thicker specimens.
When using a microscope, you typically start with the lowest power objective, often the 4x or 10x objective. This allows for a wider field of view and makes it easier to locate your specimen. Once the specimen is in focus at low power, you can then switch to higher power objectives for more detailed observation. Always ensure to adjust the fine focus when transitioning to higher magnifications to avoid damaging the slide or the lens.
Rifles typically have a smaller field of view compared to shotguns, due to their longer and narrower design. The magnification power of a rifle scope can also limit the field of view.
To locate a specimen on a microscope, you typically start with the low-power objective lens, usually 4x or 10x. This magnification provides a broader field of view, making it easier to find the specimen. Once located, you can switch to a higher power objective lens for more detailed observation. Always ensure to use the coarse focus knob with low power and the fine focus knob with higher magnifications for clarity.
WHY IS IT IMPORTANT THAT THE IMAGE IS CENTERED IN THE FIELD OF VIEW BEFORE SWITCHING TO A HIGHER POWER
Centering the image on a microscope before switching to a higher power ensures that the object of interest stays in the field of view. This helps maintain focus and prevents the risk of losing sight of the specimen when magnifying it further.

The low power objective lens on a microscope typically provides a magnification of around 10x. This lens is used for initial focusing and locating objects on a slide at a lower magnification before switching to a higher magnification lens. It offers a wider field of view compared to higher magnification lenses.
Moving the letter e to the center of the low power field helps to ensure that it remains within the field of view when transitioning to high power. This adjustment prevents the specimen from being lost or moving out of sight when switching to a higher magnification.
You should typically start with the lowest power lens (usually 4x or 10x) on a microscope to locate and focus on your specimen. This allows you to have a wider field of view and better control over the focusing before switching to higher power lenses for more magnification.
When you change from low power to oil immersion high power on a microscope, the field of view decreases. This is because high power objectives have a narrower field of view due to higher magnification, leading to a more detailed but smaller area being visible through the lens.
Centering the specimen before switching to high power on a microscope helps ensure that the area you want to observe is in focus and at the center of the field of view. This is important because high power magnification has a narrower field of view and lower depth of field, making it more challenging to locate and focus on the specimen if it is not first centered.
The low power objective lens is usually a 10x lens and it is used to orient the specimen and get it focused before switching to a higher power lens.
