How do microscopes work?
Compound Microscopes Turn the revolving turret (2) so that the lowest power objective lens (eg. 4x) is clicked into position. Place the microscope slide on the stage (6) and fasten it with the stage clips. Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward.
What are the three things a microscope must do?
To be useful, a microscope must accomplish three things: it must magnify the object you are trying to view, resolve the details of the object, and make these details visible.
What lens is used in a microscope?
convex lenses
Microscopes use convex lenses in order to focus light.
How do you view a specimen under a microscope?
Scan the slide (right to left and top to bottom) at low power to get an overview of the specimen. Then center the part of the specimen you want to view at higher power. Rotate the nosepiece to the 10x objective for 100x magnification. Refocus and view your specimen carefully.
What objective is used at the start for viewing the specimen?
When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power. Etc.
What lens is used in camera?
In a photographic camera, a convex lens of larger focal length is used.
What type of lens does a camera have?
Focal length size guide
| Focal Length | Type of Lens | What is it used for? |

| 85mm – 135mm | Short telephoto | Street photography and portraits |
| 135mm+ | Medium telephoto | Sports, wildlife, action |

Find two tubes with different diameters. Look for tubes made of sturdy materials, such as PVC. This will ensure that your microscope will hold up over time.
What can you see with a 1000x microscope?
At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up. Below is a list of your field of view at different magnifications. Field of view is how much of your specimen or object you will be able to see through the microscope.
How does a microscope magnify the image of an object?
The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is. A microscope is an instrument that can be used to observe small objects, even cells.
What is a a microscope used for?
A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles.
