Microscopes

Carl Zeiss contributed to the first microscope by making the lenses better.

captured softly with strangeness and clean and clear the eye piece and adjust the setting of it very sincerely.

the stage is the small glass piece on the microscope.

There are a variety of microscope types, but two large and different types are electron microscopes and optical microscopes. Optical microscopes are cheaper, and are commercially available for even you to buy. They work with lenses, and in many cases, oil emulsions. Electron microscopes work by bombarding specimens with electron beams. They are significantly more expensive than optical microscopes, but give a better quality image and come with vastly superior magnification levels, due to the fact that electrons have wavelengths circa 100,000 shorter than photons, or light. This enables you to see things in much greater detail.

the high power lens uses a lot of light scorce so it could burn your eyes

Another name for the light microscope is the optical microscope.

It enables you to zoom in on things that you cannot see with the naked eye

The power of a microscope magnification is the eye piece power times the objective lens so 10X eye piece times 10X objective is 100 power Common eyepieces are 10x 15x, 20X. The limit is about 2000X in an excellent unit. Average practical use is about 1000X to 1400X In expensive scopes the higher power objective lenes as 100X are made from oil not glass.

Zacharias Janssen and his son Johannes (Hans), spectacle makers in Holland, are usually credited with inventing the first compound microscope in about 1590. (Hans Lippershey, a spectacle maker in the same city, Middelburg, Netherlands, also claimed credit for the invention but was perhaps more instrumental in the creation of the telescope.)

It was said that the Zacharias Janssen was experimenting with ways to improve spectacles for people who needed greater magnification to improve eyesight, but nothing more specific than simply experimenting with multiple lenses can be associated with how he invented the compound microscope. It is worth noting that at the same time experimentation by other spectacle makers and lens makers was leading to the discovery of the telescope, another optical instrument of two lenses.

Two decades later, Galileo Galilei built a compound microscope and changed the lens design lens (convex and concave lens).

very far

No, when using the scanning power objective lens on a microscope, only one colored thread will be in focus at a time due to the limited depth of field at this magnification. The other threads will appear blurry.

A one-lens eyepiece called worn by the British is typically referred to as a monocle. It is a single lens that is worn in one eye for magnification purposes. Monocles were popular during the 19th and early 20th centuries as a fashion accessory, especially among the British upper class.

The first three things observed under the microscope were probably microorganisms like bacteria or protozoa, plant cells, and animal cells. These discoveries revolutionized our understanding of the natural world and laid the foundation for the field of microbiology.

Although the Lab Manual describes it, here it is...

Iris Diaphragm: used to regulate the amount of light entering the lens system.

Coarse-adjustment knob: used to raise or lower the body tube of the microscope.

Fine-adjustment knob: used to bring specimen into sharp focus.

Condenser: controls the maximum numerical aperture and to move the condenser itself.

Mechanical stage control: used to adjust the slide vertically and/or horizontally to bring slide into central opening of the objective.

you must multiply the two lenses getting a total of 150X

There are two basic types scaning electron microscope (SEM) which will show the surface of the subject and TEM which reveals the density.

and because your gay

The inverted image on your microscope is caused by only having one lens on magnification, the convex magnificaton with the concave eyepeice causes the light to be fliped, accually, that's the way your eye recives it, it accually would be right-side up if your eye didn't flip it.

If you're talking about the color, then that's a totally different story, its mainly because that your eye(or camera) is too close to the light and it can only see it in odd ways, since the light is coming from the bottom of the specimen, it seems to make them look all black, so that also adds to the strange effect. Hope that answers your question.

the optical system of a microscope is the objectives

A microscope's general use is high powered magnification; it can also be used for forensic purposes(fingerprints, DNA samples, etc.); or scientific purposes (I.E. disections); or health.

The simple answer is that microscopes allow the invisible to become visible. Many items that cannot be seen with the unaided eye come into focus when viewed under a microscope. Examples would include bacteria or viruses that cause infection, crystalline structures that can cause gout and even a person's own white blood cells invading other tissues as occurs in inflammatory diseases.

As an analogy, think of a telescope. You can see much more of the moon's surface through binoculars or a telescope than you can with your eyes alone. This is true for smaller objects viewed through a microscope.

Always carry the microscope by putting one hand under the shoe-shaped base and grasping the curved stand that supports the tube and its lenses with the other hand.

Everything should be in working order, clean and oil free of dust.

If you have a slide with a prepared sample, place it on the stage of the microscope.

To maintain the good condition of your microscope, first and foremost guard it from dust.

Cover the microscope with a plastic hood when you are not using the instrument and always store it in its case.

Clean the microscope carefully to avoid the scratch in the lenses. If some of the lenses have fingerprints, clean them either with lens paper or with some alcohol and a cotton swab.

Rinse dirty slides and cover glasses in liquid detergent and warm water.

The electron microscope has an eyepiece lens, tube, revolving turret, coarse focus, fine focus, objective lens, rack stop, arm, stage, and an illuminator.
