Solution for high-resolution Hyperspectral Imaging
ProScan-HSI

ProScan-HSI is the newest process-dedicated system developed by LLA Instruments GmbH & Co. KG (LLA).
Based on the combination of LLA´s high performance hyperspectral imagers, a rapid scanning table and an optimised line-illumination system, ProScan-HSI is the perfect solution for laboratory users or process developers who want to perform rapid chemical imaging analysis of small to medium-sized samples, at high spectral and spatial resolution.
The transportable scanner unit is fully compatible with any of the hyperspectral cameras in LLA´s portfolio, hence allowing to work on various wavelength ranges from 400 nm until 2.2 µm, depending on the application. ProScan-HSI can also be equipped with two different optics, giving either access to a wide field of view (320 mm), or to a
higher spatial resolution (down to 50 µm/pixel).
The system was developed to offer the highest level of modularity in terms of spectral bandwidth and resolution, along with user-friendliness:
■ Position the sample on the scanning table,
■ Start the scan and
■ Within seconds the results of the analysis are available.
Of course, ProScan-HSI is fully compatible with the data-processing software suite developed by LLA, and can also be delivered with the Prediktera´s software EVINCE for quick and easy visualisation.
LLA offers a variety of pre-configured applications for different industries. Customised application design is available upon request.

Chemical Imaging Applications
Application Example of qualitative and quantitative Analysis of Poultry
The high spatial resolution provided by ProScan-HSI, combined with the high sensitivity of the hyperspectral cameras of LLA´s portfolio allows to perform semi-quantitative analysis using chemical imaging methods. For example, it is possible to perform a mapping of the protein, fat and water content of non-processed meat for the food industry, with the advantage of using a quick and non-destructive method.
Application Example of quantitative Analysis
Relative quantitative measurement of chlorophylle content in leaves
Application Example of qualitative Analysis
Detection of contaminants in a sample of corn
