光学镜头成像规则

光学镜头有两种 :凸透镜和凹透镜. 凸透镜成像规则是: 如果物体不在焦点之外, the inverted real image will present in other side of convex focus, 真实图像有三种: 减小尺寸, 相同尺寸, 并放大 .

如果物体距离较小, 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.
