Optical Microscope / Light Microscope

As a biology laboratory instrument or tool, light microscope uses visible light to detect and magnify very small objects and enlarge them. They use lenses to focus light on the specimen, magnifying it thus producing an image. The specimen is normally placed close to the microscopic lens. The functionality of the light microscope is based on its ability to focus a beam of light through a specimen, which is very small and transparent, to produce an image. The modern types of light microscopes include: bright field light microscope, phase contrast light microscope, dark-field light microscope and fluorescence light microscope.
