Several Imaging Rules Of Convex Lens

Mar. 22, 2019

The law of convex lens imaging is an optical law. In optics, an image that is concentrated by actual light and that can be rendered on a light screen is called a real image; an inverse extension line of light converges, and an image that cannot be rendered on a light screen is called a virtual image. Let's take a look at several imaging laws for convex lenses.

1. When the object is located outside the focal length of the lens object, a reduced inverted real image is formed outside the focus of the image and within the focal length of the image;

2. When the object is located at twice the focal length of the lens object, an inverted real image of the same size is formed on the image side double focal length;

3. When the object is within the focal length of the object of the lens, outside the focus, an enlarged inverted real image is formed outside the image twice the focal length;

4. When the object is at the focal point of the lens object, the image cannot be imaged;

5. When the object is located within the focus of the object of the lens, the image side is also formed without image, and an enlarged erect virtual image is formed at a position farther than the object on the same side of the object side.
