Abstract

In the spectrum range of middle wave infrared region (MWIR) and the long wave infrared region (LWIR) radiation, the infrared spectral imaging technology is far from mature in comparison with its counterpart in visible region because infrared radiation is relative weak, the corresponding solid-state detectors and dispersive elements are extremely expensive. The paper reports a novel configuration that exploits the abundant chromatic aberration of binary optical lens to create a dual band infrared imaging imager. The design method of spectrum-dividing systems is presented for infrared imaging spectrometer. The system was analysed and evaluated by optical design software ZEMAX, theoretical formulas were then established. The practical design shows that the system has the very simple optical design that enables a very low cost lightweight robust dual band infrared imaging spectrometer.
