Paper Abstract

Applications for imaging spectrometers are expanding to cover a broader spectral range with higher fidelity, often from the VNIR to the SWIR with one common aperture. These fore-optic systems range from short focal length refractive optics for micro-UAV platforms, to large all-reflective telescopes for surveillance systems. Off-the-shelf lenses and standard prescription telescopes typically do not have the telecentricity and color correction performance to meet foreoptic system requirements for low distortion and broadband operation. This paper evaluates several wide- and narrowfield VIS-SWIR fore-optics designs, describes the effects of fore-optics aberrations on spectrometer performance, and outlines the effects of these constraints on aperture, spectral coverage, and optimal packaging.
