The Compound in Compound Microscopes

A compound microscope has two or more lenses for greater magnification - the better to see small objects. The compound is about better viewing aided with technical add-ons.

The Better View

Before the compound microscope was invented, scientists had to content themselves with the simple microscope which actually worked like a magnifying glass. But thanks to the simple microscope; creative minds set to work to improve the simple microscope. The discovery that two convex lenses provided a better magnification led to the improvements on the simple microscope and finally the compound microscope was born.

The current compound microscopes are hybrids of several microscopy functions. Expect to see several designs and models in Toronto shops. Among the top-sellers are Carl Zeiss, Leica, Olympus, Nikon, and Meiji but imported microscopes from China are getting a big share of buyers who prefer cheaper yet accurate microscopes.

A compound microscope's basic design consists of convex lenses fitted on the ends of a hollow tube. This tube is attached to rotary or adjustable nosepiece. On the adjustable stage, under the nosepiece, the object can be viewed through the lenses. If the simple microscope was a sophisticated version of the magnifying glass, then the compound microscope does better than that, magnifying objects 2000x.

The light beam from the light source, usually a mirror, passes through the window of the adjustable stage and when it hits the object to be viewed, the object stands out in strong contrast against the background. The sales representative will demonstrate how the illumination is adjusted for viewing control and if you want some modifications, you can ask for a quote for an assembled compound microscope; in Toronto dealers provide quotes customized assembly upon request.
