MUSES9-HS is a full frame, tunable filter-based hyperspectral imager, offering incomparable light throughput (94%) and tuning range (370-1000nm). Within a few dozen of seconds, MUSE9-HS automatically acquires a hypercube image stack comprising up to 126 (extendable to 315) sharply focused, 6.4-megapixel spectral images, collectively containing 6.4 million spectra.
The full- frame, tunable filter operation is clearly advantageous over line scanning or push broom traditional technologies, especially when examining static, two dimensional scenes. This is because bulky mechanical scanners are no longer required, to the benefit of portability, set up simplicity, versatility and direct adaptability to all kinds of lenses, microscopes and telescopes.
The heart of MUSES9-HS hyperspectral imager is an electro-optic tunable filter module, which automatically selects and tunes the imaging central wavelength. The tunable filter 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).
The MUSES9-HS imager acquires up to 140 (extendable to 300) spectral images, spanning an ultrawide (370-1000nm) spectral range. 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.
The MUSES9-HS electro-optic tunable filter has a polarization independent principle of operation, which results in a superb light throughput capacity. 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%).
The MUSES9-HS camera combines high spectral resolution with spatial resolution. The camera’s silicon CMOS sensor captures each spectral image with 6-megapixel spatial detail, which means that the acquired spectral cube contains 6 million spectra, with each spectrum being sampled with up to 140 (extendable to 300) points.
The MUSES9-HS imager can also be operated as a configurable multispectral imaging system, for acquiring critical spectral bands dedicated to specific applications, for improving data handling efficiency and workflow.
The MUSES9-HS has a universal C-Mount thread but accepts almost all universal thread lenses with adapters. It can also be adapted to all kinds of microscopes or telescopes.
MUSES9-HS comes with an advanced software suite and all necessary accessories that ensure turnkey operation by non-experts. The complete system is light weighted and portable, allowing for examining samples in their natural location
