Abstract
For infrared optical systems a point spread function pt (or Pd ) is calculated in terms of the spot diagram obtained through geometrical ray trace (or the theory of Kirchhoff diffraction). Also is calculated the ratio T of the energy passing through the system onto the exit window, to the total energy radiated from a plane target into the entrance pupil. Formulas are derived separately for the following different cases: a circular or rectangular ring diffraction pupil, a blur of equivalent intensity distribution or a Gaussian blur, and a circular or rectangular field stop.
