WebThe scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays. WebFeb 16, 2024 · A light microscope may also be referred to as an optical microscope. It uses light, at approximately the 400 to 700 nm wavelength to illuminate the objects under view. The lenses are made of glass, and the image is formed by the absorption of light. Light microscopes are lightweight and fairly small. They do not operate under a vacuum.
