The SisuCHEMA system from Specim Ltd. is a complete, ready to use chemical imaging workstation. SisuCHEMA merges SWIR, NIR or VNIR spectroscopy with high resolution imaging to provide multi-faceted information on chemical constituents, quantities and spatial distribution. This system includes pre-installed data acquisition and processing software, a moving sample tray and illumination. SisuCHEMA contains a built-in white reference and a built-in focusing target. More detailed information on SisuCHEMA components is available in the components sections.
The SisuCHEMA uses a push-broom hyperspectral high speed line camera. It obtains and assembles the image and wavelength information line-by-line from the sample on a computer controlled moving stage. The same hyperspectral technology, using the same cameras and similar light sources, can apply to online process monitoring or other applications where samples are in continuous motion, as in most manufacturing processes. The SisuCHEMA also serves as a feasibility system to explore the potential use of hyperspectral imaging in the process.
A unique feature of the SisuCHEMA is a light-tothroughput ratio that is 10 to 20 times higher than any other acousto-optic tunable filter (AOTF) or liquid-crystal tunable filter (LCTF) based staring array imager. The result is significantly higher speed imaging under analogous illumination conditions.
Unlike other systems, the samples move beneath the camera, thus, the SisuCHEMA only requires line illumination on the sample. The sample movement combined with line illumination provides considerable reduction in the heat load to the sample, avoiding sample damage. This contrasts with staring array systems, in which the entire sample must be illuminated throughout the entire measurement.
All SisuCHEMA systems consist of a high-performance hyperspectral camera and a computer-controlled hyperspectral scanner stage with sample height adjustment. The camera height itself is also adjustable to accommodate different lenses and to capture a narrower or wider line using the same field-of-view lens. The system comes complete with: • High-performance hyperspectral lens set • Optimized line-illumination source • Integrated computer and control module • Camera controller, ChemaDAQ™ data collection software • Optional Evince Image™ processing chemometric software • Built-in focusing grid and automated referencing • Optional Validation System
Pharmaceutical and other regulated industries require equipment validation. The SisuCHEMA Validation System includes the necessary standards, software components to perform the IQ/OQ/PQ evaluations and the required documentation for proper validation of the complete system.
