Microscope Bench with Monitor

A light microscope and a tall electron microscope stand side by side on a lab bench. The electron microscope sends its image to a monitor, where a virus particle and a pollen grain appear in detailed three-dimensional form.

In the picture

  1. Eyepiece of the light microscope: a small circular view of the specimen.
  2. Glass slide on the light microscope stage: the specimen under the lens.
  3. Tall column of the electron microscope: the upright body that guides the electron beam.
  4. Monitor screen: a three-dimensional virus particle and a textured pollen grain.

Examples

  • A school science lab comparing a light microscope with an electron microscope.
  • A research lab using a computer monitor to study tiny structures in three dimensions.

Quiz: Microscope Bench with Monitor (Age 14)

    • They can be made into flat slides without using a computer.
  3. Where does the electron microscope send its image, according to the card?

    • To the glass slide on the light microscope stage
    • To the eyepiece of the light microscope
