The lens in an electron microscope focuses and magnifies the electron beam to produce high-resolution images of tiny objects.
In an electron microscope, the condenser lens is comparable to the condenser lens in a light microscope, as both concentrate and direct the light/electron beam onto the specimen. The objective lens in an electron microscope is similar to the objective lens in a light microscope, as both magnify the specimen image. Additionally, both types of microscopes have a stage where the specimen is placed for observation.
Instead of a standard lens, the electron microscope uses a magnetic field to bend electrons. This magnetic field focuses and directs the electrons to create images with much higher resolution than traditional light microscopes.
An electron microscope uses electromagnets to focus an illuminating beam of electrons instead of glass lenses. This type of microscope offers higher magnification and resolution compared to traditional light microscopes.
In an electron microscope, magnification occurs through the use of electromagnetic lenses that focus and control the electron beam. These lenses work similarly to optical lenses in light microscopes by bending and focusing the electrons to produce a magnified image of the sample. By controlling the electromagnetic fields within the lens, the electron microscope can achieve much higher magnification than a traditional light microscope.
To change the magnification lens on a microscope, first, ensure that the microscope is turned off. Then, gently unscrew or detach the existing lens from the microscope. Carefully insert the new lens in its place and secure it in position. Finally, test the new lens by turning on the microscope and adjusting the focus as needed.

A microscope with more than one lens is known as a compound microscope. It typically consists of an eyepiece lens and objective lenses. The combination of these lenses allows for higher magnification and resolution compared to a simple microscope with just one lens.
A light microscope is an optical microscope. That differentiates it from an electron microscope, a quantum mechanical tunneling microscope and others.
Keep the lens from having condensation form on it.
In a light microscope, the condenser lens focuses and directs light onto the specimen to illuminate it. In an electron microscope, the condenser lens focuses and directs a beam of electrons onto the specimen to create the image. The electron microscope uses electromagnetic lenses to manipulate the electron beam, while the light microscope uses glass lenses to manipulate light.
Objective lens - Primary lens that magnifies the specimen placed on the stage.
The electron microscope has an eyepiece lens, tube, revolving turret, coarse focus, fine focus, objective lens, rack stop, arm, stage, and an illuminator.
