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.

Stereo Microscope – Parts, Types and Uses

A compound microscope is a microscope that uses multiple lenses to enlarge the image of a sample. Typically, a compound microscope is used for viewing samples at high magnification 40 - x , which is achieved by the combined effect of two sets of lenses: the ocular lens in the eyepiece and the objective lenses close to the sample. Light is passed through the sample called transmitted light illumination. Larger objects need to be sliced to allow this to happen efficiently. Compound microscopes usually include exchangeable objective lenses with different magnifications e.

Also known as a stereoscopic microscope, a dissecting microscope is a type of optical microscope commonly used for studying three-dimensional objects 3-D objects as well as for dissecting biological specimen e. The main identifying characteristic of stereo microscopes is the fact that they contain two separate light paths with each of the light paths providing a different viewing angle. As a result, the user gets to observe three-dimensional images of the object under investigation. Depending on the microscope, the stand may either be a hollow, cylindrical rod or a rigid arm with a cuboid shape elongated cuboid. The power cord for incident illumination may be located, or originate from, the upper-most part of the stand allowing the specimen to be illuminated from above. This feature is particularly common at the front part of a rigid arm.

A stereo microscope is not new. It has been around for a while now. It is also called a dissecting microscope and stereoscopic. It provides a 3-D view of the specimen. Each eye has separate objective lenses and eyepieces. What sets it apart from a compound microscope is that it has a lower magnification and longer working distance.

Microscope Parts & Specifications

The stereo , stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly different viewing angles to the left and right eyes. This arrangement produces a three-dimensional visualization of the sample being examined. The stereo microscope is often used to study the surfaces of solid specimens or to carry out close work such as dissection , microsurgery , watch-making , circuit board manufacture or inspection, and fracture surfaces as in fractography and forensic engineering. They are thus widely used in manufacturing industry for manufacture , inspection and quality control. Stereo microscopes are essential tools in entomology. The stereo microscope should not be confused with a compound microscope equipped with double eyepieces and a binoviewer.

Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year more history here. The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope versus an electron microscope. The simplest optical microscope is the magnifying glass and is good to about ten times 10x magnification. Ocular eyepiece lens to look through. Objective lens, closest to the object. Before purchasing or using a microscope, it is important to know the functions of each part. This information is presented below.

There are two main types of light microscope, compound and stereo. Generally stereo microscopes are used for low magnification applications, tyically upto around x. There are two optical paths transfering the image from the eypieces al the way to the to the final objective lens and even all the way to the sample, for some very low cost units.

Also features other versatile parallel-optics type models suitable for various applications and Greenough-type models that are user-friendly and affordable. These models meet the increasing needs for imaging systems that span spatial scales from single cells to whole organisms. The SMZ25 can seamlessly capture the entire dish while simultaneously delivering microscopic details.

Боюсь, что в ТРАНСТЕКСТЕ завелся какой-то неизвестный вирус. - Вирус? - снисходительно хмыкнул Стратмор, - Фил, я высоко ценю твою бдительность, очень высоко. Но мы с мисс Флетчер проводим диагностику особого рода.

До поворота оставалось еще триста метров, а такси от него отделяло всего несколько машин. Беккер понимал, что через несколько секунд его застрелят или собьют, и смотрел вперед, пытаясь найти какую-нибудь лазейку, но шоссе с обеих сторон обрамляли крутые, покрытые гравием склоны. Прозвучал еще один выстрел. Он принял решение. Под визг покрышек, в снопе искр Беккер резко свернул вправо и съехал с дороги. Колеса мотоцикла подпрыгнули, ударившись о бетонное ограждение, так что он едва сумел сохранить равновесие. Из-под колес взметнулся гравий.

Он что-то скрывает. Джабба вытаращил глаза: - Мидж, дорогая. Я по уши опутан кабелем. Если ты хочешь назначить мне свидание, я освобожусь. Если же нет, то позвони электрикам.
