Summary
| Description |
English: Principal planes of a thick lens. The principal points as their locations on the optical axis are marked H and H'. The front and rear focal points of the lens on the axis are F and F' respectively. If both sides of the lens are a same medium (e.g., the lens in air or vacuum), then H and H' are coincident with the nodal points N and N'. |
