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 … 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.

WebFeb 18, 2024 · The thin lens equation shows the relationship between the image distance ( di i ), object distance ( do o ), and the focal length ( f) of the lens.
