Five Imaging Laws of Microscope Convex Lens
1. When the objective lens is beyond the double focal length of the object side of the lens, a reduced inverted real image will be formed within the double focal length of the image side and outside the focal point;
2. When the objective lens is on the double focal length of the object side of the lens, an inverted real image of the same size will be formed on the double focal length of the image side;
3. When the objective lens is within twice the focal length of the lens object side and out of focus, a magnified inverted real image will be formed outside the double focal length of the image side;
4. When the objective lens is on the focal point of the lens object side, the image side cannot form an image;
5. When the objective lens is within the focal point of the object side of the lens, no image will be formed on the image side, and a magnified upright virtual image will be formed on the same side of the lens object side as it is farther from the object.
