While most people picture the compound model from lab class when they think of microscopes, many types of microscopes are actually available. These useful devices are employed by researchers, medical technicians and students on a daily basis; the type they select depends on their resources and needs. Some microscopes provide greater resolution with lower magnification and vice versa, and they range in cost from tens to thousands of dollars.

Microscope

There are a number of different types of microscopes and each of them solves unique problems. Below you will find information on the five different types of microscopes along with the applications for each microscope and just who might use each instrument.

Below each description of the microscope and its use is an image that was captured using that particular microscope. Stereo microscopes are used to look at a variety of samples that you would be able to hold in your hand. A stereo microscope provides a 3D image or "stereo" image and typically will provide magnification between 10x - 40x. The stereo microscope is used in manufacturing, quality control, coin collecting, science, for high school dissection projects, and botany.

A stereo microscope typically provides both transmitted and reflected illumination and can be used to view a sample that will not allow light to pass through it. The following are samples often viewed under a stereo microscope: coins, flowers, insects, plastic or metal parts, printed circuit boards, fabric weaves, frog anatomy, and wires.

This image of a penny was captured under the a coin collecting stereo zoom microscope at 20x magnification. A compound microscope may also be referred to as a biological microscope.

Compound microscopes are used in laboratories, schools, wastewater treatment plants, veterinary offices, and for histology and pathology.

The samples viewed under a compound microscope must be prepared on a microscope slide using a cover slip to flatten the sample. Students will often view prepared slides under the microscope to save time by eliminating the slide preparation process. The compound microscope can be used to view a variety of samples, some of which include: blood cells, cheek cells, parasites, bacteria, algae, tissue, and thin sections of organs.

Compound microscopes are used to view samples that can not be seen with the naked eye. The magnification of a compound microscope is most commonly 40x, x, x, and sometimes x. Microscopes that advertise magnification above x should not be purchased as they are offering empty magnification with low resolution. This image of mushroom spores was captured under a compound biological microscope at x magnification.

Inverted microscopes are available as biological inverted microscopes or metallurgical inverted microscopes. Biological inverted microscopes provide magnification of 40x, x and sometimes x and x. These biological inverted microscopes are used to view living samples that are in a petri dish.

An inverted microscope allows the user to place the petri dish on a flat stage, with the objective lenses housed beneath the stage. Inverted microscopes are used for in-vitro fertilization, live cell imaging, developmental biology, cell biology, neuroscience, and microbiology.

Inverted microscopes are often used in research to analyze and study tissues and cells, and in particular living cells. Metallurgical inverted microscopes are used to examine large parts at high magnification for fractures or faults.

They are similar to biological inverted microscope in the magnification provided, but one primary difference is that the samples are not placed in a petri dish, but rather a smooth side of the sample must be prepared so it can lay flat on the stage.

This smooth sample is polished and is sometimes referred to as a puck. Metallurgical microscopes are high power microscopes designed to view samples that do not allow light to pass through them. Reflected light shines down through the objective lenses providing magnification of 50x, x, x, and sometimes x.

Metallurgical microscopes are utilized to examine micron level cracks in metals, very thin layers of coatings such as paint, and grain sizing. Metallurgical microscopes are utilized in the aerospace industry, the automobile manufacturing industry, and by companies analyzing metallic structures, composites, glass, wood, ceramics, polymers, and liquid crystals. This image of a piece of metal with scratches on it was captured under a metallurgical microscope at x magnification.

Polarizing microscopes use polarized light along with transmitted and, or reflected illumination to examine chemicals, rocks, and minerals. Polarizing microscopes are utilized by geologists, petrologists, chemists, and the pharmaceutical industry on a daily basis. All polarizing microscopes have both a polarizer and an analyzer. The polarizer will only allow certain light waves to pass through it.

The analyzer determines the amount of light and direction of light that will illuminate the sample. The polarizer basically focuses different wavelengths of light onto a single plane.

This function makes the microscope perfect for viewing birefringent materials. This is Vitamin C captured under a polarizing microscope at x magnification. If you are unsure which type of microscope might be best for your application, contact Microscope World. Types of Microscopes.

Compound Microscopes A compound microscope may also be referred to as a biological microscope. Inverted Microscopes Inverted microscopes are available as biological inverted microscopes or metallurgical inverted microscopes. Metallurgical Microscopes Metallurgical microscopes are high power microscopes designed to view samples that do not allow light to pass through them.

Main Types of Microscopes

Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path , by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe.

Compound Microscope

There are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes. Some types are best suited for biological applications, where others are best for classroom or personal hobby use. Outside of light microscopy are the exciting developments with electron microscopes and in scanning probe microscopy. Below is a brief introduction of the different types available. For further information and guidance in your search and to find microscope reviews please continue reading about each type by following the corresponding links. Commonly binocular two eyepieces , the compound light microscope , combines the power of lenses and light to enlarge the subject being viewed. Typically, the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses, which can be rotated into the field of view, produce higher magnification to a maximum of around X generally.

Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник.  - Может, чего-нибудь выпьешь. - Нет, а-а… нет, спасибо, сэр.  - Ему трудно было говорить - наверное потому, что он не был уверен, что его появлению рады.  - Сэр, мне кажется… что с ТРАНСТЕКСТОМ какая-то проблема.

Она инстинктивно отпрянула назад, застигнутая врасплох тем, что увидела. Из-за решетчатой двери кухни на нее смотрели .

Последний месяц был для Лиланда Фонтейна временем больших ожиданий: в агентстве происходило нечто такое, что могло изменить ход истории, и, как это ни странно директор Фонтейн узнал об этом лишь случайно. Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена. Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил. Стратмор был блестящим специалистом, возможно, лучшим в агентстве.

 - Может, все-таки чего-нибудь выпьете. Беккер понимал, что, по мнению бармена, ведет себя странно. - Quiere Vd. Algo? - настаивал бармен.  - Fino.

 Чепуха. Ты никогда не смог бы проникнуть в почту коммандера. - Ты ничего не понимаешь! - кричал Хейл.  - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами.  - Этот жучок вмонтировал кто-то другой, и я подозреваю, что по распоряжению директора Фонтейна.

И повернулся к офицеру. - Вы уверены, что в коробке все его вещи. - Да, конечно, - подтвердил лейтенант.
