Abstract
Infrared detector technology has progressed to include many fused wavebands. This has been driven by the need of military systems to image over diverse spectrums. Imaging systems can now operate in both the short wave infrared (SWIR) as well as the long wave infrared (LWIR). Reflective optics seems like a natural solution to such a large waveband, but they will have more restrictive size and field of view constraints. This paper will demonstrate the steps to achieve a Petzval lens with fast aperture and moderate field that is achromatic in the SWIR and has low axial color in the LWIR. The lens achieves a high resolution solution in terms of modulation transfer function (MTF).
