The lens is the object used to focus light in a light microscope. The lens in a light microscope is typically found within the objective lens or the eyepiece, and it helps to magnify the image of the specimen.
A lens is used to bring an object into focus. The shape of the lens helps to bend light rays in such a way that they converge at a single point, resulting in a clear image.

A lens is an object made out of glass or plastic that is able to bend light rays by refraction. Lenses are commonly used in cameras, microscopes, eyeglasses, and other optical devices to focus or manipulate light.
The fine adjustment knob is used to bring the image of the object on the slide into focus. It allows for small, precise movements of the lens to sharpen the image.

A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. A hand lens can be used to magnify an object to make it easier to see or also to focus light.

A light source on a microscope helps make the object that you're looking at easier to see. It brightens up the view so the object can be seen more clearly and can be more "in focus".
Lens
The wavelength of light used to observe an object must be shorter than the size of the object itself.
Parfocality is the term used to indicate that when an object is in focus at low magnification, it will also remain in focus at higher magnifications without the need for refocusing.
