1. A MidWave InfraRed (MWIR) lens device for remote sensing comprising, in order, from a remote object to an image plane:
a first optical group having a positive optical power;
a second optical group having a positive optical power;
a third optical group having a positive optical power;
an aperture stop (AS); and
a focal plane array (FPA);
wherein the lens is corrected over a spectral waveband of 3.3 μm to 5.1 μm, distortion is completely corrected at 0.85 of maximum field, angular field of view is 33.6 degrees, focal length is 9 inches, and F # is 2.64;
whereby an image is formed.
