3 SPECIM IN Revevenue k Core AISA Sisu Established in 1995, Spin-off from VTT Located in Oulu, Finland International team of 55 people Established, long term customer relationships > 95% of the products exported

4 SPECTRAL IMAGING

5 SPECTRUM Spectrum is defined as the intensity of light as a function of wavelength It can be presented for example as: Emission spectrum Reflectance spectrum Absorption spectrum Transmission spectrum Material dependent Due to the molecular structure Photons are absorbed and this causes rotation and vibration of water molecules (heating the sample) 5

6 WHAT IS HYPERSPECTRAL IMAGING?

7 Purpose of Spectral Imaging Spectral Imaging is used to detect individual material-dependent features or fingerprints due to specific chemical bonds in different materials. The ultimate goal Complete spectrum is collected at every position of the samples Detect different materials - Qualitative and Quantitative analysis Spectral and Spatial distribution 7

8 HOW TO PRODUCE HYPERSPCETRAL DATA

9 PUSH-BROOM APPROACH A line-scan device Full spectra of the all spatial positions along the imaged line is recorder in one single snapshot Target must be imaged line-by-line to form the 2D image

10 PUSH-BROOM APPROACH N17E

11 HOW TO AQUIRE 2D SPECTRAL IMAGES? Sensor with 2D detector array Imaging spectrograph with input slit Fore objective Line light source Sample stage

12 PUSH-BROOM APPROACH Pushbroom is the preferred technology selection for most spectral imaging applications Pushbroom technology provides ca times higher light throughput than tunable filters Illumination can be focused times more efficiently On-line application Need for simultaneous spectral data in each pixel with a moving target or moving instrument Moving webs and conveyer belts Same technology in outdoor measurements, laboratory and final application

13 WAVELENGTH RANGES Specim is providing push-broom hyperspectral imaging devices for the following wavelength ranges Fenix UV ( nm) VIS ( nm) Raman ( nm/ nm) { VNIR ( nm) Extended-VNIR ( nm) NIR ( nm) SWIR ( nm) MWIR (3 5 um) LWIR (8 14 um)
