Where are objective lenses located?

The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube.

What are the magnifying parts of microscope?

They have an objective lens (which sits close to the object) and an eyepiece lens (which sits closer to your eye). Both of these contribute to the magnification of the object.

How does a light microscope work?

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.

The basics of using a microscope tells us that we should start with the lowest power objective first and with the stage at its lowest position.

Which Way Do I Turn the Knob?

If your eyepiece (s) on your microscope is built facing away from the arm of the microscope then turning the knob away from you will raise the stage and turning the knob towards you will lower the stage.

How to Adjust Tension

Some microscopes will come with a tension adjuster. This allows you to manipulate the tension of the adjustment knob to determine how soft or how hard do you have to turn the knob to attain the desired level of movement from each revolution of the knob.
