# What makes the field of view larger on low power?

## What makes the field of view larger on low power?

Compensate with the light control (sometimes called the iris diaphragm ). The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power.

Why is locating an object more difficult if you start with high-power objective?

Why is locating an object more difficult if you start with high-power objective than with the lower power objectives The field of view is smaller with higher-power objectives than with low-power objectives. The smaller field of view makes it more difficult to locate objects.

### Why does the depth of focus decrease with higher power?

Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. The amount of light transmitted to your eye is greatest at the low power.

What happens when you switch from low power to high power?

When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

#### Why is the field of view on low power?

The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

Why does depth of focus decrease with higher power?

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus.

Why is locating an object more difficult if you start with high-power objective than with the lower power objectives The field of view is smaller with higher-power objectives than with low-power objectives. The smaller field of view makes it more difficult to locate objects.

## What happens to the field of view on a low power microscope?

The field of view is widest on the lowest power objective. When you switch to a higher power, the field of view is closes in. You will see more of an object on low power. The depth of focus is greatest on the lowest power objective.
