The initial testing of prototype multiple-order-diffraction engineered (MODE) lens telescope is essential process before the sky test to evaluate the optical imaging performance of a space object. Prototype MODE lens telescope consists of MODE primary lens which is a core component to correct secondary spectrum, a field lens and a double Gauss type color corrector and achieves a diffraction limited performance. The performance is tested on the diffraction efficiency with respect to supercontinuum laser wavelength on an optical testbed and evaluated on the polychromatic performance for prototype molded ring segment.
