This image shows the parts of an Olympus CX-31 microscope.  The same parts are present in roughly the same places on any good quality Bright Field Compund Light microscope.  However, there will be slight difference between different manufacturers and models of microscopes. 

Video tutorials that show the different parts of the Olympus BHT and Olympus CX-31 microscopes can be found on the Video Tutorials page of this website.
