The conventional interferometer is mainly composed of double slits and focusing lens, but the lens will inevitably produce chromatic aberration, For the Hefei Light Source HLS II, this paper proposes to replace the first focusing lens in the original interference light path with an RC structure focusing mirror. The second single lens is replaced with a doublet lens to reduce dispersion and geometric aberration without changing the optical axis of the optical path. So as to improve the imaging quality of the optical path. PB - JACoW Publishing CP - Geneva, Switzerland ER -
