Show moreThis note calculates the lateral chromatic aberration in a singlet coronagraph objective lens in order to quantify the amount of over occulting that will be required for a lens as a function of focal ratio and wavelength range of the observations. The over occulting will set a lower limit to the coronagraph field-of-view. This note also calculates the requirements on the coronagraph bandpass limiting filter. Show less
