What do you use a light microscope for?

Simple light microscopes use a single lens to magnify an object and cannot reach high magnification. Compound light microscopes use two sets of lenses - an objective lens and an eyepiece - to produce images. Monocular microscopes have one eyepiece, while binocular microscopes have two eyepieces and reduce eye strain.

Accordingly, how does a light microscope work and what happens?

The user looks through the microscope eyepiece. A mirror at the bottom of the microscope reflects light rays up to the object through a hole in the stage. Objective lenses magnify the image which is made even larger when it is seen through the eyepiece lenses. Others can magnify hundreds of times, or thousands.

What is a light microscope for?

The light microscope, so called because it employs visible light to detect small objects, is probably the most well-known and well-used research tool in biology. Yet, many students and teachers are unaware of the full range of features that are available in light microscopes.

What is a microscope and how does it work?

The eyepiece lens (the one closest to your eye) magnifies the image from the objective lens, rather like a magnifying glass. On some microscopes, you can move the eyepiece up and down by turning a wheel. This gives you fine control or "fine tuning" of the focus. You look down on a magnified image of the object.
