Abstract
Design forms are disclosed for infrared imaging systems that can operate at hyper-hemispherical fields of view (e.g., up to 270.degree.) and at wide relative apertures (e.g., up to f/0.7) to produce images having low distortion--typically no more than 20% greater than the distortion resulting when the image size is proportional to the field angle.
