The image produced by the compound microscope is upside down and reversed. A Real Compound Microscope Designed for Kids 8. As the wavelength of an electron can be up to 100000 times shorter than that of visible light photons electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects.
The electron microscope depends on electrons not light to view an object.

The most commonly used microscope for general purposes is the standard compound microscope. Eyepieces typically have a magnification between 5x 30x. Prepared specimen slides can be purchased to fit the classroom subject matter or user can make his own specimen slides.
It has a series of two lenses. Optical microscopes can be simple consisting of a single lens or compound consisting of several optical components in line. Magnification of the Image of the Object by Compound Microscope 3.
A compound microscope can resolve down to about 02 μm. When the microscope is in perfect alignment and has the objectives appropriately matched with the substage condenser then we can substitute the numerical aperture of the objective into equations 1 and 2 with the added result that equation 3 reduces to equation 2. 3 Magnification Levels – 40x 100x 400x.
In this article we will discuss about- 1. Modern TEMs can visualise objects as small as the diameter of an atom. Eyepiece ocular lens with or without Pointer.
