Abstract In order to meet the integrated application requirements of full-spectrum hyperspectral
imaging and detection, the optical design of visible-to-long-wave infrared co-aperture imaging
spectrometer is carried out in this paper. The image square telecentric objective is realized by
off-axis three reflection structure , and its four spectral segments are divided by the combination
of field of view separation and beam splitter; The magnifications of the MWIR and LWIR
spectrometers are set to and to meet the design specifications and i
