摘要：

We designed and fabricated a flat multi-level diffractive lens (MDL) that is achromatic in the SWIR band (875 nm to 1675 nm). The MDL had a focal length of 25 mm, aperture diameter of 8.93 mm, and thickness of only 2.6 mu m. By pairing the MDL with a SWIR image sensor, we also characterized its imaging performance in terms of the point-spread functions, modulation-transfer functions, and still and video imaging.
