MUSES9-HS

Overview

Cutting Edge Hyperspectral Imager

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 126 (extendable to 315) 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 2 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 6.4-megapixel spatial detail, which means that the acquired spectral cube contains 6.4 million spectra, with each spectrum being sampled with up to 126 (extendable to 315) 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

Value Proposition

Portability and set up simplicity

State-of-the-art line scanning or push broom hyperspectral imagers are best suited to applications employing line scan cameras. A typical example is the inspection of objects transported by a conveying belt in production lines. Here, the natural motion of the objects serves the purpose of the spatial scanning required.

MUSES9-HS can effectively accommodate both static and moving scenes. In static scene applications, particularly, no external mechanical scanners are required. This simplifies setups and maximizes portability, thus expanding the usability of hyperspectral imaging to the vast number of applications that are addressed with conventional full frame cameras.

Direct adaptability to all kinds of lenses, microscopes and telescopes

MUSES9-HS is a full frame, real time spectral imager and has a universal c-mount thread. As such, it directly adapts to all kinds of lenses, microscopes and telescopes, converting them to powerful analytical instruments.

Incomparable data quality

In line scanning/push broom imagers, the spatial resolution is limited to 500-900 pixels per spatial dimension, due to slit and scanning mechanism restrictions. On the contrary the typical spatial resolution of MUSES9-HS is 6.4 megapixels and can exceed 50 megapixels in custom configurations.

Superb light efficiency

The mean light efficiency (throughput) of the grating-based line scanning/push broom imagers is about 40%. MUSES9-HS tunable filter technology has a clearly superior light efficiency reaching the value of 94%, which remains substantially flat across its entire operation spectral range. The direct consequences of such a figure are the achievable ultrahigh acquisition speeds and the suitability for low light apps, such as fluorescence microscopy.

Real time spectral imaging and data acquisition flexibility

Line scanning/push broom imagers are incapable of providing live spectral imaging, because spectral images are calculated with the post processing of the acquired spectra. Some practical setups employ a color camera for focusing before scanning. MUSES9-HS offers video-rate spectral imaging at any desired wavelength. Besides focusing, it comprises an instant visualization aid of invisible target features, of static or moving targets or of dynamically changing phenomena. Moreover, if offers the flexibility of preconfiguring the system to acquire a subset of user-defined critical spectral bands (multispectral operation), thus optimizing data handling.
