VERS 50504 68 2006 MODE SEQ NAME Wavelength-compensation of diffracted encircled energy NOTE 0 The optical system comprises a spherical mirror focused to infinity, thus showing some spherical aberration. The three plots of encircled energy are for wavelengths from 0.25 to 1.0 micron. At longe NOTE 0 r wavelengths, the normal Airy pattern is larger, but aberrations are smaller in terms of wavelengths and so send less energy into the outer rings. This leads to encircled energy plots that are reaso NOTE 0 nably close to each other over the whole range of wavelengths. The situation of being fairly near the diffraction limit but having a range of wavelengths to deal with is not unusual. When this compe NOTE 0 nsation effect applies, it means that the the optical design is not constrained to solve a worst case at one end of the spectrum, and it validates the constant sampling frequency given by the pixel si NOTE 0 ze in an image sensor. (Images that were purely diffraction-limited would differ in size by 4:1 in this case.) In the layout here, a ZEMAX feature draws a mirror substrate of visible thickness.
