CETI's Compound Microscopes deliver fantastic images.

They use a lens close to the object being viewed to collect light (called the objective lens) which focuses a real image of the object inside the microscope.

That image is then magnified by a second lens or group of lenses (called the eyepiece) that gives the viewer an enlarged inverted virtual image of the object.

The use of a compound objective/eyepiece combination allows for much higher magnification, reduced chromatic aberration and exchangeable objective lenses to adjust the magnification. A compound microscope also enables more advanced illumination setups, such as phase contrast.
