The light microscope is a very powerful tool for understanding the structure and function of tissues, and it is widely used in biomedical science courses, as well as in research and diagnostic laboratories. Understanding the capabilities and limitations of the light microscope is important if one is to get the best results from microscopy. The ability to identify structures and specific cell types has been greatly aided by different staining techniques and more recently by immunohistochemistry. The investigation of cell structure has also been considerably extended by the developments in electron microscopy and fluorescence microscopy.
