  1. Microscope

  2. An instrument used to see objects that are too small for the naked eye to see.

  3. SimpleLight Microscope Is similar to magnifying glass and has only one lens.

  4. Compound Light Microscope Uses compound lenses to magnify objects. The lens bend or refract light to make the object beneath them apprear closer.

  5. Binocular (Stereoscopic) microscope Has binocular (two eyes) viewing of larger specimens which give three dimensional view of an object.

  6. Electron Microscope

  7. Eyepiece Lens:  the lens at the top that you look through.  They are usually 10X or 15X power.  Tube:  Connects the eyepiece to the objective lenses Arm:  Supports the tube and connects it to the base

  8. Base:  The bottom of the microscope, used for support Stage:  The flat platform where you place your slides. 

  9. Revolving Nosepiece or Turret:  holds two or more objective lenses and can be rotated to easily change power Objective Lenses:  Usually there are 3 or 4 objective lenses on a microscope.  They almost always consist of 4X, 10X, 40x, 100X powers. 

  10. Diaphragm:  Thediaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. 

  11. Light source:  A steady light source used in place or a mirror. Coarse adjustment knob: Focusing the lens with low magnification Fine adjustment knob : Focusing the lens with high magnification

  12. Magnification Microscope has 3 magnifications: Scanning, Lowand High. The magnification of each objective lenses is indicated and written on it. In addition to this, the ocular lens (eyepiece) has also its own magnification.

  13. Total Magnification The total magnification of a specimen can be calculated by: Ocular lense magnification multiplied to the objective lense magnification.
