It is an instrument that has two lenses (set of two lenses) these lenses is objectives and ocular. Furthermore, they use visible light as a source of illumination.

This is a 100x (100 times) objective lens. Also, this lens is small in order to attain high resolution and magnification. Furthermore, due to its size, it is important for the lens to get as much light as possible.

We use it to bring the specimen in perfect focus once the specimen is visible through the course-focusing knob. Also, focus slowly to avoid contact between the objective and the specimen.

These scopes use ultraviolet light to illuminate specimens that fluoresce. Besides, mostly, a fluorescent antibody or dye is added on the viewed specimen.

It is in the back of the microscope and supports the objectives and ocular. Also, it is the part that we use to carry or lift it.

This scope uses a special condenser that allows the examination of structures inside the cells. Also, they use a compound light. Furthermore, these microscopes take advantage of different refractive indexes for the examination of live organisms. In addition, the final image produced by these microscopes is a combination of light and dark.

It refers to an optical instrument that uses a lens or an arrangement of lenses to magnify an object. Also, they help to view different organisms. Furthermore, the light of a microscope helps to see microorganisms.

In 1021, Scientist named Alhazen developed the first magnifying glass. It can be used to make text bigger and easier to read.  It is also used to study microscopic organisms, but those are complex ones. Magnifying glasses magnify objects and this ability allows us to see bacteria, viruses, etc.

Moreover, by immersion of lens in oil it eliminates the refraction of light, it happens because the glass and oil have almost the same refractive index. Most noteworthy, in this way the light is maximized and gives the clearest image. Besides, It oil immersion lens is used without oil then the produced Image will become unclear and has a poor resolution.

Magnifying Glass

It’s the bottom of the scope. In addition, it houses the light source and the back section of base acts as a handle to carry the scope.

We use it to adjust the position of objective lenses. Also, this should be done keeping in mind that the objective should not hit the slide. In addition, it should be stopped when the object is completely visible through the ocular.

The glass (hand lens) is a convex lens, which makes objects appear larger than they actually are. This is because their convex lens i.e. lens curved outside, refract or bend light rays to converge. When light bounces off an object and travel to the eyes, these convex lenses bend the parallel rays so that they converge and create a virtual image on your eyes retinas.

It is a scope that instead of light uses a flow of electron to produce an image. Moreover, this microscope enhances the images of viruses, protein, lipids, ribosomes, and even small molecules.

It is scientific equipment that magnifies very small objects that are not visible to the naked eyes. Furthermore, with the help of a microscope, we can see the various organism that we cannot see or study.

They are used in different fields for different purposes. Some of their uses are tissue analysis, the examination of forensic evidence, to determine the health of the ecosystem, studying the role of protein within the cell, and the study of atomic structure.

A magnifying glass is used to make tiniest things look bigger. It is a form of a microscope. Consisting of a single lens, it magnifies an object whenever the glass is held up to the object.  The lens is mounted in a frame.

These microscopes have a device that scatters light from the illuminator. In addition, it does this to make the specimen appear white against the black background.

The virtual image, which gets created, appears larger than the real object. This is due to principles of geometry. The eyes trace the light rays back in parallel lines to the virtual image and since the virtual image is farther from your eyes than the object is, the object appears bigger.The magnification of a magnifying glass also depends on where it is placed between the user's eye and the object being viewed. It also depends on the total distance between them.If you have a poor or low vision, then reading magnifiers will work like a charm and help you in reading a book, magazine, newspaper, etc. Nowadays, full page reading book magnifiers are also available.
