Compound Microscope

A compound microscope is an optical instrument that uses a series of lenses collect light from a sample then focus the light to create a virtual image.  At the base of the microscope there is a light source ( halogen is most common).  From this light source light travels into a condenser which focuses light onto the sample located on the stage above.  Light then passes through the sample and into the objective lens.  The user will then be able to see a virtual two-dimensional image while looking through the eyepiece.  Nikon Instruments, Zeiss Microimaging and Leica are some of the world’s leading microscope manufacturers because of the quality of glass used in the manufacturing of their objectives.  A compound microscope is most commonly used for light microscopy and with the addition of various accessories it can perform phase contrast, darkfield, and fluorescence microscopy.
