Compound microscopes
doubled lenses
A compound microscope is made up of two or more lenses in its optical system. The objective lens magnifies the specimen, and the eyepiece lens further magnifies the image produced by the objective lens. This combination of lenses allows for higher magnification and resolution compared to simple microscopes.

Yes, light microscopes use lenses to bend and focus light, allowing objects to be magnified and viewed at a higher resolution. This magnification can vary depending on the lens system and type of microscope used.
A microscope with two or more lenses is called a compound microscope. This type of microscope typically uses an objective lens to magnify the specimen and an eyepiece lens for further magnification, allowing for enhanced detail and clarity in the observed image. Compound microscopes are commonly used in laboratories and educational settings for biological and material studies.
Zeiss was active in improving the design and manufacture of microscopes, in advancing the theory of lenses and in creating new types of lens glasses. For more about him you might see his wikipedia article.
Convex lenses in microscopes help to magnify the specimen being observed by bending light rays, allowing for clearer and more detailed images. The shape of the convex lens also helps to focus the light rays onto a single point, resulting in a sharper image. Understanding the properties of convex lenses in microscopes is essential for proper functioning and accurate observation of specimens.
If a microscope has more than one lens, it is called a compound microscope.

Compound light microscopes have two types of lenses: objective lenses and eyepiece (or ocular) lenses. The objective lens is located close to the specimen and magnifies the image, while the eyepiece lens further magnifies and helps focus the image for the viewer.
Microscopes are devices which use lenses and illumination to make small things look larger and to make target objects (= things that you want to see magnified) more clearly visible. Generally, microscopes are made up of a number of different lenses which work in combination. With the illumination system, the way that the illumination is applied and the type of illumination can be changed, depending on the nature of the object to be looked at, to make it appear clearer. Regular microscopes mainly consist of two types of lenses, an objective lens and an eyepiece, as well as a stage to place the target object on and illumination system. The object that is placed on the stage is first magnified by the objective lens which is close to it. It is then further magnified by the eyepiece, making the object look larger. more
Compound microscopes have more than one lens. The first (objective) lens magnifies the object to produce an image. Subsequent lenses magnify an image produced by a previous lens. Leeuwenhoek's "microscope" had only one lens -- simple magnification only. ~The Undertaker~
