HSI pushbroom imaging systems

Hyperspectral Imager pushbroom sytems ( HSI Pushbrooms ) are highly integrated optoelectronic systems that allow to acquire hyperspectral lines. They are recording a spectral image with an imaging spectrograph and a camera, which in the first dimension has a spatial mapping and in the second dimension the spectral axis.

These systems can be preferable used in two applications:

Imaging spectroscopy with moving objects

Spectral profiles of temporally variant samples

 

Spectroscopy with high S / N Ratio

As with one exposure time typically 300 to 1000 spectra are acquired simultaneously, the signal depth increases at comparable light use and response times to conventional spectrometer systems. Thus, with comparable costs often superior measurement results to conventional linear fiber-coupled spectrometer systems can be achieved. We offer a variation of different pushbroom systems for certain spectral ranges and different applications

 

HSI Pushbroom VIS  (380 nm – 700 nm)

for high precision measurement applications in the analysis of color in the visible spectrum and UV – fluorescence appications. Especially well suited for the camera to be fixed by the C – mount lens mount on microscopes.

HSI Pushbroom VIS/VNIR  (500 nm – 980 nm)

for combined color / chemical investigations in the visible and near infrared spectral range. Especially suitable for studies on living tissue. The system can be supplied without illumination unit for integration into existing imaging systems or with integrated broadband LED lighting unit.

HSI Pushbroom VNIR extended  (800 nm – 1050 nm)

To study different organic ingredients in substances, tissue samples and other objects.

HSI Pushbroom NIR 1.7 (900 nm – 1700 nm)

Based on a Gigabit Ethernet indium gallium arsenide ( InGaAs ) camera and an imaging spectrograph for the expansion of existing NIR spectroscopy systems
