    We designed, fabricated, and characterized a flat multi-level diffractive lens comprised of only silicon withdiameter=15.2mm, focallength=19mm, numerical aperture of 0.371, and operating over the long-wave infrared (LWIR)spectrum=8µ<#comment/>mto 14 µm. We experimentally demonstrated a field of view of 46°, depth of focus><#comment/>5mm, and wavelength-averaged Strehl ratio of 0.46. All of these metrics were comparable to those of a conventional refractive lens. The active device thickness is only 8 µm, and its weight (including the silicon substrate) is less than 0.2 g.
