Microscopy is the science of investigating small objects and structures using such an instrument. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). Several helpful links to fun and interactive learning tools are included throughout the PPT and on the Smart Links slide, near the end of each presentation.

PRESENTED BY EARLY MICROSCOPES The first “microscopes” consisted of merely a tube with a plate for the object at one end and a lens which gave a magnification less than ten times the actual size. Microscopes let us view an invisible world – the objects around us that are too small to be seen with the naked eye. Microscopy began with the observation of live specimens and continues its growth with technical developments in the fields of intravital microscopy, endos-copy, and in vivo microscopy. Home.
