  3. The microscope allows us to see things from a different perspective.

  24. Parts of a Microscope

  25. Ocular Lens Course Adjustment Body Fine Adjustment Turret/Revolving Nosepiece Objective Lens Stage Clips Arm Stage Iris/Diaphragm Stage Height Adjustment Light Source Base 40X, 100X, 400X

  26. Micrometres to Millimetres 1000 µm = 1 mm

  27. Microscope Notes • Resolving Power: The ability to show separate objects as distinct. • Depth of Field: Refers to the thickness of an image that is in focus at any one time. Smaller depth of field larger depth of field

  28. Types of microscope • Simple: Has the lowest level of magnification. Uses one lens and a mirror as a light source.

  29. Compound: Uses two or more lenses and have greater magnification ability. Eyepiece magnification = 10X Highest Power Lens = 40X Total Highest power = 10 X 40 = 400X

  30. Electron: These use an electron beam to scan or pass through a sample in order to produce an image. They can achieve magnifications of up to 10,000,000 X

  31. Effects of Magnification on the Field of View (FOV): • The highest the magnification, the smallest the field diameter will be. Low power lens : Field Diameter = 4000 μm Medium power lens : Field Diameter = 1600 μm High power lens: Field Diameter = 400 μm
