AISA Kestrel
AISA Kestrel (Specim, Oulu, Finland): The Kestrel imaging spectrometer collects hyperspectral data with 2.4 nm full width half maximum (FWHM) at 1.75 nm spectral sampling intervals (356 bands in total) from 400 to 1000 nm. The lens focal length was 35.5 mm with a field of view (FOV) of 40◦.
AISA Ibis
AISA Ibis (Specim, Oulu, Finland): The AISA Ibis imaging fluorometer covers 670–780 nm with 0.245 nm spectral resolution (full width half maximum, FWHM) at a 0.11 nm sampling interval (1004 bands) and is essentially an imaging spectrometer with ultraspectral resolution. The FOV of Ibis is 32.3◦.
AISA Eagle
AISA Eagle (Specim, Oulu, Finland): The imaging spectrometer provides 400–970 nm hyperspectral images with 3.3 nm spectral resolution (FWHM). Spectral binning (approximately 10 nm) is used to increase signal-to-noise ratio (SNR) of the data. Imagery acquired with this band configuration has 63 bands across the 400–970 nm continuum.
