Hisoty of Microscopes :-

Microscopes give us a large image of a tiny object.The microscopes we use in school and at home trace their history back almost 400 years.The first useful microscope was developed in the Netherlands between 1590 and 1608.There is almost as much confusion about the inventor as about the dates.Three different eyeglass makers have been given credit for the invention.The possible inventors are Hans Lippershey (who also developed the first real telescope).Lens quality in early microscopes was often poor so the images were not very clear.But even these rather crude microscopes were a great help in learning more about animals and plants cells and micro organism.The modern technology provides us developed microscope which have been use to look at human cell, identify mineral, micro particles which is very appreciated to our scientist and laboratory.And those are used to find out the virus in medical field and the scientists can even use a microscope to figure out where illegal drugs come from.Microscopes are instruments that produce magnified images of small objects.

Type of Microscopes:-

Measuring Microscopes are used by toolmakers for measuring the properties of tools.These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view.

Biological Microscopes are used to study organisms and their vital processes.

Metallurgical Microscopes are used for metallurgical inspection including metals, ceramics and other materials.

Electron Microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition.

Optical and Light Microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects.

Digital and Video Microscopes are instruments that use digital technology to magnify images of objects.They include built-in cameras and a series of high-powered lenses that provide superior image quality and resolution.

Specialty Microscopes are designed for specific applications such as metallurgy or gemology.They use specialized techniques or technologies such as acoustics to produce magnification.

Depth Gages Microscopes are used to measure of the depth of holes, cavities or other component features.

Magnifiers Microscopes are inspection instruments that are used to magnify a product or part detail via a lens system.

Recent microscopes incorporate the lamp into the base, enabling the instrument to be moved from one place to another without upsetting the relationship of the components, so the lamp can now be added to the list of components held in alignment by the stand.

The Component Parts of the Microscope:-

It is a simple, rugged, well-made instrument of a kind that, with proper care, will still be functional after hundred of years of frequent to occasional use.

The optical components are those of all compound microscopes and even though this model has no integral lamp, this discussion will begin with the lamp and proceed in sequence via the mirror to the eye.Microscopes require, especially at the highest powers, intense illumination.The intensity of a light source depends not so much upon its absolute power as upon the amount of light emitted from a given area of the source lumens per square millimetre rather than just lumens.To achieve high intensity, various lamp designs have come and gone, but one of the commonest and most satisfactory is the low-voltage tungsten filament lamp, with the filament in the form of a tightly-wound flattened grid.

The combination of a suitable quartz-halogen bulb with a concave spherical reflector works well and is also in wide use.The mirror is used only to fold the optical path of the microscope into a convenient space.It also introduces another source of potential maladjustment into the system, and another surface to collect dust. Having said this, the mirror does not need to be of the highest optical quality to do its job, nor does a small amount of dust on the mirror make much difference to the quality of the image.A slight film of fine dust (such as remains after dusting the mirror with a blower brush) can actually be useful in locating the beam of light from the lamp when setting up the instrument. Always use the flat side of the mirror in combination with a substage condenser.The substage condenser fitted to most microscopes is of a design originated by Ernst Abbe in the late 1800s and is usually referred to as the Abbe condenser.Whilst condensers of higher correction are available, the Abbe condenser has proven to be quite satisfactory for routine microscopy.A substage condenser of some kind is an absolute requirement for serious -- or at least satisfactory -- microscopy.The objectives from x20 upwards require the subject to be illuminated evenly over quite a large angle, and neither a concave mirror nor (especially) a flat mirror is capable of achieving this. If no condenser is used with a high power objective, the result is an image which is dark, coarse, contrasty and lacking in detail -- described by earlier microscopists as "a rotten image".Lower power objectives however, can give acceptable, even quite pleasing images without a condenser if the mirror is directed toward a close, well frosted lightbulb or a bright white cloud.In practice, once the microscope has been set up, the condenser and its diaphragm setting can be largely forgotten until the objective is changed for one of higher or lower power.The specimen is usually supported by a slide and essentially at the higher powers of the biological microscope covered by a coverglass.Thus introduced into the image-forming light path, slide and coverglass become part of the optical system.The thickness of the slide is important to the correction of the substage condenser and the thickness of the coverglass is critical to the performance of the objective, especially those of higher power (x20 and greater). Most substage condensers are corrected to work with a slide thickness of 1.0mm and most microscope objectives of x20 or greater power are designed to work with a coverglass thickness of 0.17mm (thickness no. 1½).

A Laboratory Microscopes is a device that produces a magnified image of objects too small to be seen with the naked eye like different cell and minute particles. Such objects are thus called microscopic.The microscope is widely used in medicine and biology.Common microscopes use lenses and others such as electron microscopes scan an object with electrons, x-rays and other radiation besides ordinary visible light.

The laboratory microscopes compound microscope which constantly used in consists essentially of two or more double convex lenses fixed in the two extremities of a hollow cylinder.The lower lens (nearest to the object) is called the objective, the upper lens (nearest to the eye of the observer) is called the eyepiece.The cylinder is mounted upright on a screw device, which permits it to be raised or lowered until the object is in focus, which will give magnified image of every cell and particles.When an object is in focus, a real, inverted image is formed by the lower lens at a point inside the principal focus of the upper lens.
