Compound light microscope function.

The objects which are smaller than 0 3 micro meter cannot observe from compound light microscope the reason for that is the microscope using long wavelength visible light amitrano and tottora 2007. In this type of microscope there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. It is divided into structural parts and optical parts. Prior to the invention of the microscope the details of objects on slides were limited.

The microscope was created by zacharias janssen in the late 16th century. Compound light microscope optics magnification and uses with links to microscopemaster buyer s guides a compound light microscope is a microscope with more than one lens and its own light source. Its an adjustable apparatus hence controlling the light intensity and the size of the beam of light that gets to the specimen. A typical compound microscope will include a viewing lens that magnifies an object 10 times and four secondary lenses that magnify an object 10 40 or 100 times.

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. Single microscopes were similar to using a magnifying glass. A compound microscopes helps in magnifying an image in two stages. Light begins at the base of the microscope coming from the source of illumination.

As the light passes through the image of the specimen on the slide is picked up by the magnification of the objective lens above it. Its found under the stage of the microscope and its primary role is to control the amount of light that reaches the specimen. The compound light microscope contains eye piece and the objective lenses to magnify the objectives amitrano and tortora 2007. Light is placed below the sample and travels through one of the secondary lenses and the viewing lens and is thus magnified twice.

A compound light microscope is a type of light microscope that uses a compound lens system meaning it operates through two sets of lenses to magnify the image of a specimen. It uses an objective lens that has many powers on a turret and an eyepiece that helps in magnifying the image formed by the objective lens. A compound microscope utilizes multiple lenses to provide magnification. It travels upward through the condenser and aperture and passes through the stage.

Device which holds the microscope slide in place and moves it along the stage condenser group of lenses below the stage in which directs and concentrates the light beam from the lamp to the specimen. The compound microscope works by enhancing the image that is projected by the first lens with a second lens and light.
