The compound microscope works by enhancing the image that is projected by the first lens with a second lens and light. A compound microscope has multiple lenses. 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. First of all see through the eyepiece and adjust the mirror in such a way so that sufficient light is seen entering into the microscope.

Mirror is used to reflect light rays into the microscope. Made up of two lenses it is widely used to view plant and animal cell organelles including some parasites such as paramecium after staining with basic stains. The compound light microscope uses visible light for illuminating the object and contains lenses that magnify the image of the object and focus the light on the retina of the observer s eye. In its simplest form the compound microscope consists of two lenses one at each end of a hollow tube fig.

Brightfield light microscope compound light microscope this is the most basic optical microscope used in microbiology laboratories which produces a dark image against a bright background.

In this type of microscope there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. The microscope was created by zacharias janssen in the late 16th century.

Compound microscopes have furthered medical research helped to solve crimes and they have repeatedly proven invaluable in unlocking the. A compound microscope is a high power high magnification microscope that uses a compound lens system. The parts of a compound microscope work together in hospitals and in forensic labs for scientists and students bacteriologists and biologists so that they may view bacteria plant and animal cells and tissues and various microorganisms the world over. In this way a light microscope is much like a telescope except that.

A light microscope uses focused light and lenses to magnify a specimen usually a cell. It contains a plane mirror on one side and a concave mirror on the other side. Working of the compound microscope. Prior to the invention of the microscope the details of objects on slides were limited.

The objective lens typically 4x 10x 40x or 100x is compounded multiplied by the eyepiece lens typically 10x to obtain a high magnification of 40x 100x 400x and 1000x.
