s has been subjected to the most rigid scientific tests.By these the exact index of refraction and the exact degree ofdispersion of the glass are determined, and with these data availableit is possible to very perfectly correct both spherical and chromaticaberrations while still making use of wide… … yellow greenIntensity curve of the rays of the spectrum. In the correction of spherical aberration, our objectives arecorrected for light coming from the yellow-green portion of thespectrum, thus insuring correction for the light of greatest intensity;and, similarly, in correcting chromatic…
