Abstract: | It has been generally accepted that the correction of secondary spectrum aberrations, in optical imaging systems, necessarily requires the use of glasses having abnormal relative partial dispersions. This is shown to be an error, arising from defects in the accepted theory of first order chromatic aberrations. The theory of secondary spectrum correction with normal glasses is given, with a numerical example of its application. |
