It is the area that you see when looking through the microscope. The field of view depends on the strength of magnification. The lower the power the larger the field of view.

How do you calculate a microscopes field of view?
Since the field of view is a circle, the size of the field of view is it's area. You would need to find the diameter of the field of view, using a transparent ruler or a micrometer. Divide the diameter measurement by 2 to get the radius. Then use the formula for the area of a circle, Area = πr2. For example, you measure the diameter of the field of view to be 2.14mm. Divide 2.14mm by 2 to get the radius, and you get 1.07mm. Square 1.07mm, which is 1.14mm2. Multiply x 3.14 (pi), and you get 3.58mm2. So the field of view for this example would be 3.58mm2.The field of view differs with different magnifications. The lower the magnification, the larger the field of view.
What two types of microscopes view the surface of an object?
The binocular dissecting microscope and the scanning electron microscope.
What microscope is used to view medal surfaces?
Electron scanning microscopes scan metal deposited on surfaces.
When switching to a higher power lens what happens to the field of view?

How can the field of view on a compound microscope made brighter?

What is parcentric?
Parcentric is used to describe microscopes. It is the center of the field that does not go outside the inner one third of the field of view with any objective of a matched set.
What is an advantage of light microscopes compared to electron microscopes is that light microscopes?
Light microscopes allow you to view living specimens and electron microscopes do not allow this.
How are microscopes used today?
microscopes are used in labs, medical field, surgeries, astronomy and crime investigation field
What is a limitación of using electrón microscopes to view specimens?
The specimen must be dead. Electron microscopes view specimens in a vacuum- no air.

What do you view atoms with?
You can view an atom with a scanning- tunneling microscope and a atomic force microscopes.
What are the similarities between the microscopes made by Anton van Leeuwenhoek and the microscopes used nowadays?
both are bright field microscopes, and works on two lenses
What is field of view in biology?
In reference to microscopy, the field of view (or FOV) describes the area you can see through the microscope, especially light microscopes. Under low power, it is about 1800 micro metres and at high power, it is around 450 micro meters (but this depends A LOT on the microscope you are using).
Did microscopes lead to the discovery of cells?
Yes, Microscopes can view very small cells on hair, fibre and living organisms.
Can compound light microscopes view living specimen?
Yes it can.
