The color corrector (CC) system serves as an essential part of the multi-order diffractive engineered (MODE) lens system to provide near diffraction limited performance by correcting residual refractive and diffractive dispersion of MODE primary over the astronomical R-band (589 nm to 727 nm). The CC is designed to collimate and refocus the image from the MODE primary as a unit magnification relay and corrects chromatic aberrations at the same time. As a result, the system including the optomechanics of the CC is specifically designed for compensating errors from both the MODE primary and the CC. Results regarding prototyping, assembly and testing of the color corrector are reported.
