Compound Light Microscope Function

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.

Compound light microscope function.

It s an upright microscope that produces a two dimensional image and has a higher magnification than a stereoscopic microscope. Its an adjustable apparatus hence controlling the light intensity and the size of the beam of light that gets to the specimen. 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. 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.

Labeled diagram of a compound microscope. Light is placed below the sample and travels through one of the secondary lenses and the viewing lens and is thus magnified twice. Single microscopes were similar to using a magnifying glass. The compound microscope works by enhancing the image that is projected by the first lens with a second lens and light.

A compound microscope utilizes multiple lenses to provide magnification. Light begins at the base of the microscope coming from the source of illumination. 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. 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.

The compound light microscope contains eye piece and the objective lenses to magnify the objectives amitrano and tortora 2007. 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. How a compound microscope works functions. A compound microscopes helps in magnifying an image in two stages.

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. It travels upward through the condenser and aperture and passes through the stage. In this type of microscope there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. 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. 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.
