HI 90: Hyperspectral Imaging Remote Sensing System

Back to All Products

For true hyperspectral HI90_Freisteller_blauerhintergrundimaging with automatic detection and identification of compounds including VOCs, TICs and CWAs, Bruker’s HI 90 provides unprecedented sensitivity, ease of use and superior signal processing. At the heart of the HI 90 system is an FT-IR spectrometer based on a high efficiency Michelson plane mirror interferometer with active alignment. This extremely efficient interferometric system aids in providing high quality spectra with outstanding signal-to-noise ratios. Detection is performed by a 256 x 256 pixel IR focal plane array which allows near real-time images to be collected in a 3D image cube, with each pixel containing valuable spectral information of the scene recorded.  Time resolved spatial and spectral information analysis for the HI 90 is performed with Bruker’s OPUS RS software.
The HI 90 housing incudes all electronics and thermal management systems in an environmentally secure housing, requiring no external fans or extra processing boards. Simply connect to the computer through the Ethernet connection and maintain full control of the image acquisition and the HI 90 positioning from a remote distance.
