Abstract

The paraxial ray-tracing model of Fery prism is illustrated in this paper, and the three-order aberration coefficients are calculated. According to the solutions for minimal aberrations, four types of imaging spectrometers are designed based on Fery prism, accommodating for different requirements. The image quality is evaluated to ensure that MTFs are larger than 0.6 at Naquist frequencies, and the spectral resolutions are all higher than 5 nm. The advantages of these imaging spectrometers are analyzed by comparison of the volume, spectral resolution and field of view. The potential competence of Fery prism in hyperspectral imaging is indicated since the field of view and the volume have a direct proportional function. One typical system of these designs is manufactured and assembled afterwards to verify the simulation data.
