consist of a NIR camera and an imaging NIR spectrometer with a NIR corrected lens. Imaging NIR spectrometer allow high resolution images (spatial resolution) of the measurement objects. Hyperspectral cameras are cameras that provide a high spectral resolution i.e. at a large number of wavelength points the spectral intensity is measured simultaneously. More details are found on the page analytical methods.


LLA cameras are characterised by:
■ High quality spectra - based on distortion-free projecting optical components (like a specifically designed NIR lens and the designed grating of the spectrometer) with low noise levels
■ High spectral and spatial resolution of up to 320 x 256 pixel - due to powerful components (like customised sensors)
■ Unrivalled analysis speed of up to 795 Hz (Frame rate) - achieved by purpose designed electronics

Sophisticated software tools for spectra recording and data interpretation as well as analysis development kit are provided with the camera. A high performance industrial PC equipped with these software tools as well as camera control software is also included in delivery.

The NIR cameras may be combined with a RGB camera providing color information additional to the NIR spectral information of the measured object.

Each NIR camera can be equipped with an illumination unit. The illumination unit PMAmsi was developed especially for LLA NIR cameras and ensures that the light is optimally focused in the measurement plane of the camera. A high intensity of the measurement signal is thereby achieved. These components are combined by an installation bridge. The installation bridge allows precise alignment of camera and illumination unit. Required electrical components, e.g. power supplies and control PC are installed in a separate control cabinet.

The complete setup is usually mounted above a conveyor belt. The aim is the detection at high spectral resolution and fast evaluation of material streams on the conveyor belt. At frame rates of up to 795 Hz and with a spatial resolution of up to 320 tracks across the conveyor belt, even bulk material with objects of a few millimetres in diameter is measured and analysed.

In addition to the NIR hyperspectral cameras, a hyperspectral imaging system for the UV-Visible spectral range is available.

The uniSPEC0.9HSI hyperspectral camera is designed exhibiting a spectral range from 350nm to 950nm. Based on a high-sensitivity configurable CMOS sensor, this camera can be customised to meet the end user’s requirements. Whether high speed, high spatial resolution, broad wavelength range
(Δλ = 600nm) or very high spectral resolution (below 0.4nm per pixel) is preferred, all options are configurable.

The outstanding performance of the spectrometer is complemented by a series of available optics which have been carefully selected for offering the highest optical performance (distortion-free, chromatic correction, high throughput) possible.

As for its NIR counterparts, the UV-Visible hyperspectral camera uniSPEC0.9HSI is delivered with a full software package permitting control of the camera system, acquisition, export and post-processing of the data. With its high sensitivity and its high resolution, this hyperspectral camera gives access to a whole new range of possible applications.

The uniSPEC0.9HSI hyperspectral camera is available in two models:
■ uniSPEC0.9HSI_s, 400 nm wavelength range & suitable for compact setups with large field of view
■ uniSPEC0.9HSI_w, with an enhanced 600nm wavelength range & working on a reduced field of view
