The EO filter automatically selects and tunes the imaging center wavelength. It is synchronized with the imaging sensor module so that several narrow band images are captured during a spectral scanning.
In the image domain, the data set includes a full image at each individual wavelength. In the spectroscopy domain, a fully resolved spectrum at each individual pixel is recorded. The nature of imagery data is typically multidimensional, spanning spatial and spectral dimensions (x, y, λ).
Shift in focus, due to chromatic aberrations are perfectly compensated with an embedded autofocusing system, so that all the collected hypercube images are sharply focused. The minimum nominal tuning step is 3 nm and scanning time ranges between 30s-50s, depending on scene’s illumination intensity/shutter speed.
Advantages of electro-optical tunable filter technology in hyperspectral cameras:
- full use of the spectral range of the CMOS (Si) or InGaAs sensor in UVA - VIS - NIR – SWIR (unlike Fabry-Perot filter technology, or certain push-broom technologies)
- use of lenses with C thread (C-mount) so as not to compromise neither the field of view nor the focusing distance (unlike hyperspectral imagers by F-P filter or interferometry + Fourier transform among other technologies)
- polarization independent, allowing a high filter light throughput. It transmits 94% of the incoming light at any given active spectral band, while, at the same time, rejecting all the out-of-band wavelengths with an incredible blocking efficiency exciding 4 OD (T=0.00001%).
- combines high spectral resolution with high spatial resolution. Each spectral cube contains 6.4 million spectra (6.4 MP sensor), with each spectrum being sampled with up to 126 (extendable to 315) points: 126/315 spectral bands
- user configurable as multispectral imaging system: for acquiring critical spectral bands dedicated to specific applications, for improving data handling efficiency and workflow
- can effectively accommodate both static and moving scenes

Additional advantages of the ISC-Muses9-HC hyperspectral camera:
- powerful camera control and spectral image and hypercube processing software at no extra cost
- optional spectral maps: represent with a color (fake, not real) all pixels of the same spectral class (similar spectral characteristics).
