We then find the appropriate surface shape needed to satisfy this requirement. a. CONCAVE MIRROR, ONE CONJUGATE AT INFINITY We first consider the concave mirror shown in Fig. 8. Parallel rays are incident from the left with all rays focused at a distance/ from the mirror vertex. For convenience we let / /, and A be positive quantities. Applying Fermat's Principle to a ray on the optical axis and a ray at height y, we see that equal OPLs require If = l + {f - A), or / = / + A. From the geometry in Fig.

The reasoning used to arrive at Eq. 1) and an estimate of the minimum possible image size is not a rigorous procedure, nor does it tell how the light is distributed within the image. A more rigorous approach requires analysis using diffraction theory, a topic we consider in some detail in Chapter 10. REFERENCES Allen, C. (1973). Astrophysical Quantities, third edition, Chap.
