WebFigure 2. Primary and secondary principal planes of a thick lens. A1 and A2 are the vertexes. Computation of the position of the image of a given object at a given distance from the thick lens is facilitated by determining the positions of two planes inside the lens, known as the principal planes. They are defined as follows: WebPositive m < 1. Table 16.3 Three Types of Images Formed by Lenses.
