Abstract
A conceptual design has been developed for a Low-light Cloud Imager (LCI) to be used on a combination NOAA/DoD weather satellite. This lens was specified to have a ground resolution of 2.4 km over a 1 10 °x7 1 ° field of view. In order to accomplish this resolution on the night-side ofthe earth in the visible/near-infrared waveband (400-1000 nm), a very fast (f/1.72) lens was required. This paper describes the requirements on the lens, the effort to design a lens to meet the requirements, and the resulting performance of the conceptual design. Special attention is given to the following areas: understanding the performance requirements, simultaneously accomplishing a wide field of view and a low f-number, color correction, and distortion correction.
