How do light microscopes work
WebThe light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to … WebCompound microscopes have two lenses that work together to produce high-magnification images of the object. The light source brightens the specimen with the help of the …
