摘要：
A hybrid diffractive-refractive infrared lens of Germanium was fabricated by means of diamond turning, in which the diffractive surface was produced on an aspheric substrate. Test results for the hybrid lens and a comparative lens without the diffractive structure showed that the diffractive surface was fabricated with good accuracy. It effectively reduced the chromatic aberration of the single lens system, and significantly improved the image quality of the system, which corresponds well to the design result.
