Microscopy

Before exploring the parts of a compound microscope , you should probably understand that the compound light microscope is more complicated than just a microscope with more than one lens. First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens that cannot be seen by the naked eye. Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens. Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.

Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope vs. The simplest optical microscope is the magnifying glass and is good to about ten times 10X magnification. Basic parts of the microscope:. They are usually 10X or 15X power. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. Stage clips hold the slides in place.

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. It is not definitively known who invented the microscope. However, the earliest microscopes seem to have been made by Dutch opticians Hans Janssen and his son Zacharias Janssen and by Dutch instrument maker Hans Lippershey who also invented the telescope about

Microbiology, the branch of science that has so vastly extended and expanded our knowledge of the living world, owes its existence to Antony van Leeuwenhoek. In , with the aid of a crude microscope consisting of a biconcave lens enclosed in two metal plates, Leeuwenhoek introduced the world to the existence of microbial forms of life. Over the years, microscopes have evolved from the simple, single-lens instrument of Leeuwenhoek, with a magnification of , to the present-day electron microscopes capable of magnifications greater than , Microscopes are designated as either light microscopes or electron microscopes. The former use visible light or ultraviolet rays to illuminate specimens. They include brightfield, darkfield, phase-contrast, and fluorescent instruments. Fluorescent micro-scopes use ultraviolet radiations whose wavelengths are shorter than those of visible light and are not directly perceptible to the human eye.

Он был совсем один и умирал естественной смертью. - Странно, - удивленно заметил Смит.  - Обычно травматическая капсула не убивает так. Иногда даже, если жертва внушительной комплекции, она не убивает вовсе. - У него было больное сердце, - сказал Фонтейн.

Стратмор кивнул: - Думал. Но решил этого не делать. Сьюзан так и подумала. Старшие должностные лица АНБ имели право разбираться со своими кризисными ситуациями, не уведомляя об этом исполнительную власть страны. АНБ было единственной разведывательной организацией США, освобожденной от обязанности отчитываться перед федеральным правительством. Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине.

Щелчок взведенного курка. - Adids, - прошептал человек и бросился на него подобно пантере. Раздался выстрел, мелькнуло что-то красное.

 Да. Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли. Похоже, этот канадец рассмотрел его довольно внимательно.

Стратмор холил и лелеял Сьюзан, оберегал. Он заслужил. И теперь наконец ее получит.

 - Маловероятно. Помимо всего прочего, в списке очередности указано, что это посторонний файл.
