In a Scanning Electron Microscope (SEM), electron lenses, particularly an electromagnetic lens, are used to focus the electron beam onto the sample. The beam is finely focused using a combination of condenser lenses and objective lenses, which help control the beam's diameter and convergence. Additionally, scanning coils are employed to direct the focused beam across the sample surface for imaging. This precise focusing is crucial for obtaining high-resolution images of the sample's topography and composition.

Can a Scanning Electron Microscope be used on living specimens?
No, a Scanning Electron Microscope (SEM) cannot be used on living specimens because the high vacuum and electron beam used in an SEM would quickly kill the specimen. For observing living specimens, a different type of microscope, such as an optical microscope or a specially designed environmental SEM, should be used.

What objective lens shows greatest depth?
The scanning electron microscope (SEM) has the greatest depth of field compared to other objective lenses in optical microscopes. This is because the SEM uses a focused beam of electrons to create an image, allowing for a larger range of depths to be in focus simultaneously.
