Règles d’imagerie des lentilles optiques

There are two kinds of optical Lens :convex lens and concave lens. Convex lens Imaging rule is: if objects is out of the focus, the inverted real image will present in other side of convex focus, there are three kinds of real image: size reduced, the same size, and amplified .

If the Object distance is smaller, the image distance will be larger, then the real image will also be greater;

If Objects put inside focus, the magnified virtual image will present on the same side of the focus of convex,

If the Object distance are larger, the image distance will be bigger , and the virtual image are also bigger; The Effects of concave lens is for light is emission, the imaging rules is much more complex than convex lens.
