A light microscope is a laboratory tool that uses visible light to magnify and detect small objects. It uses lenses to focus light on the specimen, which produces an image. The resulting image can be captured digitally, imaged on a photographic plate, or detected directly by the eye.  Light microscopes can be used for a wide range of applications to examine small samples. By adapting the illumination and imaging technique to the specific use case, high-resolution images can be obtained.  Some types of light microscopes include: Bright-field Light Microscope Phase Contrast Light...
