Using Zmax, it is determined that the the functional form of the geometrical blur function b(x) can be approximated by a Gaussian function (1) = e-x+20 with a variance o2 = 10 um?. If we also approximate the impulse response of the diffraction of the system by another gaussian with o equal to half the first zero of the Airy pattern, what must the F# of the system be at 1=0.5 um to have the variance of the combined ray+diffraction distortion be less than 15 um? (Note: This answer to the problem is about 3 lines long.)
