File Name: different types of microscopes and their functions .zip
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.
Microscope , instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis. Although optical microscopes are the subject of this article, an image may also be enlarged by many other wave forms, including acoustic , X-ray , or electron beam , and be received by direct or digital imaging or by a combination of these methods. The microscope may provide a dynamic image as with conventional optical instruments or one that is static as with conventional scanning electron microscopes. A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses.
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. The simple microscope is generally considered to be the first microscope. It was created in the 17th century by Antony van Leeuwenhoek, who combined a convex lens with a holder for specimens.
Compound Microscope. Stereo Microscope. Other Types of Microscopes. Objective Lenses. Eyepiece (Ocular) Condenser Lens (Sub-stage Condenser) Diaphragm. Illumination Systems (Light Source).
Various types of microscopes are available for use in the microbiology laboratory. The microscopes have varied applications and modifications that contribute to their usefulness. The light microscope. The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object.
Тогда он дотронулся до его руки.
Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой. Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло. В данный момент эта чертова программа надежно зашифрована и абсолютно безопасна. Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал. Сьюзан должна была признать, что, услышав о Цифровой крепости, она как ученый испытала определенный интерес, желание установить, как Танкадо удалось создать такую программу.
