Compact hyperspectral scanning system

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.

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
