What are the differences between a light microscope a compound microscope a stereoscopic light microscope a transmission electron microscope and a scanning electron microscope? A light microscope uses a series of lenses to focus light allowing small objects to appear larger.
What microscope does not use light in forming the specimen image? This is the electron microscope, which uses a beam of electrons instead of light. Electrons have a much shorter wavelength than visible light so they can separate points which â¦ are closer together than the light microscope can ie they have a better resolution and so can see more detail.
