  LIGHT MICROSCOPY Modern microscopes are compound light microscopes. This means that there are 2 lenses that  magnify, the ocular lens and the objective lens. Light rays provide the illumination.    Brightfield microscopy--- this is the most common use of the light microscope. Specimens are  usually stained to make them more easily visible.  Light rays pass though the condenser lens and  are directed straight up into the objective lens, passing through the specimen on the way.  The  field of view, seen through the ocular, is brightly illuminated, with the specimen appearing  slightly darker if unstained, or brightly colored due to dyes.   The total magnification provided can be determined by multiplying the ocular magnification  times the objective magnification. The very best compound light microscope might have a top  magnification near 2000X.
