A thin lens is an optical element with zero thickness that has refracting power. It is almost always used in air (n = n' = 1.0) and is characterized by its focal length f. An object at infinity is imaged to the Rear Focal Point of the lens F'.

Both foci are located a distance from the optic centre, where is the focal length of the lens. The image produced by a diverging lens can be located using the ... WebFor a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens. For a converging lens (for example a convex lens ), the focal length is positive and is the distance at which a beam of collimated light will be focused to a single spot. WebA thin symmetrical lens has two focal points, one on either side and both at the same distance from the lens. Another important characteristic of a thin lens is that light rays through its center are deflected by a negligible … ipic houston phone number

Web4. Well the short answer, is that there is NO minimum object distance for a lens. The object distance can be anywhere from - infinity to - 0 . I assume you are using the normal left to right convention, so all object distances are negative. And if you are not assuming "thin lenses" the you really are in trouble. WebThe image must be real, so you choose to use a converging lens. The focal length can be found by using the thin-lens equation and solving for the focal length.
