Microscopes

Overview of Light Microscopy

  • Stereomicroscope:

    • Examines entire objects in three dimensions at low magnification.

    • Also referred to as a dissecting microscope.

  • Compound Light Microscope:

    • Used for examining small or thinly sliced sections of objects at high magnification.

    • Termed "compound" because it relies on the use of two sets of lenses.

Electron Microscopy Analogies

  • Transmission Electron Microscope:

    • Analogous to the compound light microscope in its application and structural focus.

  • Scanning Electron Microscope:

    • Analogous to the dissecting light microscope (stereomicroscope) in its focus on surface structure and three-dimensional perspective.

Microscopy Performance Metrics

  • Resolution:

    • Defined as the minimum distance between two objects at which they can be seen as distinct and separate.
