How does a microscope work simple?
A simple light microscope manipulates how light enters the eye using a convex lens, where both sides of the lens are curved outwards. When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye. This makes the object look bigger than it actually is.
How does a microscope work ks3?
microscopes, also called light microscopes, work like magnifying glasses. They use lenses, which are curved pieces of glass or plastic that bend light. The object to be studied sits under a lens. As light passes from the object through the lens, the lens makes the object look bigger.

The classic compound microscope magnifies in two steps: first with an objective lens that produces an enlarged image of the object in a 'real' image plane. This real image is then magnified by the ocular lens or eyepiece to produce the virtual image.

How to use a microscope?
Extra Tips and Tricks 1 Here are some more useful tips to consider before using a microscope: 2 When using a microscope with a single eyepiece, it is good practice to keep the other eye open to avoid eye strain. Remember that the image is flipped upside down and horizontally when viewed through the microscope, so when moving it, it will appear to go the opposite way to what you might intend – moving the slide up makes the image move down, and moving the slide to the right makes the image move left, etc. 3 Prepare your slide with a protective coverslip. 4 Do not touch the middle glass part of the lenses with your fingers, just the edges. There is special lens paper for cleaning the lenses. You may want to use gloves. 5 Switch off the microscope when it is not in use. 6 Always cover your microscope when not in use. 7 Always use both hands when you carry a microscope, with one hand on the arm and the other under the base.

How to get a microscope lens to come into focus?
You may need to slightly adjust the focus and centering of the object you are viewing. If you try this, and it doesn’t seem to come into focus, then drop the lens to very near, but not touching, the slide (look from beside the microscope to do this, not through the eye piece) and then look through the eyepiece while you slowly raise the lens away from the slide. At some point, it will come into focus for you.

How to adjust diopter?
To further improve your viewing experience, you can do a few of the following advanced steps: 1 Diopter Adjustment: A diopter is useful if you are someone who usually wears glasses. The diopter is designed so you have slightly different focus in one eye than the other. If you know one eye is slightly blurrier than the other, adjust the diopter behind your eyepiece until both eyes are in perfect focus. 2 Condenser Adjustment: You may also achieve better quality images if you adjust your condenser and iris diaphragm. This can make the lighting better, but also help to reduce the foggy fuzzy outlines around your images.
