The Different Parts Of A Microscope

Posted by


The compound microscope was originally invented in 1590 by Zacharias Janssen, a Dutch optician. Also known as a light microscope, the compound microscope gives you a close-up view of tiny structures like cells, bacteria, and other small components.

The Various Parts Of A Compound Microscope

Eyepiece

As you may have been able to guess, the eyepiece is an ocular lens that helps you see magnified images. Most compound microscope lenses can magnify specimen or samples up to 10 or 15x.

Eyepiece Tube

This is the part of a compound microscope that connects the eyepiece with the objective lens.

Objective Lenses

On most laboratory microscopes there are three or four objective lenses attached to the end of the eyepiece tube. These lenses tend to range from 4x to 100x magnifying powers, but this will vary from microscope to microscope.

Stage

The stage is the platform on the microscope where you place your slides. Most of the time there are stage clips attached to the stage to help keep slides in place.

Illuminator

This is a steady light source that you can find at the very base of the microscope. There is a mirror that reflects light from the outside source through the bottom of the stage. This is used to illuminate the specimen on the slide.

Diaphragm or Iris

The diaphragm or iris of a compound microscope can be found directly underneath the stage. This piece can be rotated to vary the intensity of the cone light that is being projected upward toward the slide.

Coarse Adjustment Knob

The coarse adjustment knob can help you focus on the specimen in the slide by adjusting the distance of the objective lens. When you turn the knob, it will move the lens up and down until you can see the magnified image clearly.

Fine Adjustment Knob

When you need to move from one objective lens to another, you turn the fine adjustment knob. This lets you view the slide under high or low magnification.
