An electron microscope uses a beam of electrons to illuminate a specimen

Changing objectives is made possible by the flexibility in goal-setting. By reassessing priorities, shifting resources, or modifying timelines, objectives can be adjusted to align with new circumstances or evolving strategies. Open communication, clear decision-making processes, and a willingness to adapt are crucial in facilitating changes to objectives.
eyepiece
The objective lens of a microscope has the power to magnify the image. By changing the objective lens to one with a higher magnification, the image will appear larger when viewed through the eyepiece.
The different levels of magnification. It makes it easier for you to recognize the magnification you want without having to read the numbers on the side.
Microscope
The body tube of a microscope moves up and down by rotating the coarse focus knob, which adjusts the distance between the objective lens and the specimen. This movement allows for focusing and changing the magnification level when examining a specimen under the microscope.
A microscope magnifys or makes things look bigger than they are.
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
