This magnification value determines the diameter of the field of view when the low power objective is used. A microscope's field of view refers to the diameter of the circular optical light that is visible when viewing an object under the microscope. This value forms an inverse relationship with magnification, which means that increasing the magnification results in the reduction of the field of view.
The viewer spins the nosepiece to select different objective lenses. Objective lenses: One of the most important parts of a compound microscope, as they are the lenses closest to the specimen. A standard microscope has three, four, or five objective lenses that range in power from 4X to 100X. When focusing the microscope, be careful that the objective lens doesnât touch the slide, as it could break the slide and destroy the specimen. Specimen or slide: The specimen is the object being examined.
