Hyperspectral Imaging Systems | Photon ETC | Headwall Photonics

Hyperspectral imaging is a technique combining spectroscopy and imaging, where each image is acquired at a narrow band of the electromagnetic spectrum. As an example, the human eye sees light in three bands (red, green and blue) of the visible spectrum while hyperspectral imaging divides the spectrum in more bands, typically covering the visible and near-infrared range.

The term hyperspectral imaging refers to the continuous acquisition of narrow bands (< 10 nm) across the electromagnetic spectrum. With our unique technology we are able to obtain bands of 2nm-4nm wide and even 0.3nm. On the contrary, multispectral imaging covers only a discrete number of bands, and is often performed with a filter wheel.

Through the analysis of the spectral and spatial information contained in each pixel of the image, it is possible to identify unique spectral signatures and assign them to the components of the sample under investigation. For example, the material or tissue analyzed can be mapped according to its molecular components.

Hyperspectral Microscopy

Photon ETC’s hyperspectral Microscopy is designed for researchers developing the next generation of nanomaterials, such as upconverting nanoparticles for cellular imaging. 

Wide-field Hyperspectral Imager

Widefield hyperspectral imager allows the view of spectral analysis by providing complete spectral information for each and every pixel of a full resolution image.

Infrared Cameras

Providing both InGaAs & HgCdTe infrared (IR) cameras, the ZephIR & Alizé™ series best capable for achieving low noise high frame rate by using the unique 4-stage TE cooler (deep cooling down to -80°C), while the BOREA uses rotary Stirling micro cooler.

Tunable Source Filters

The Laser Line Tunable Filter (LLTF) is a non-dispersive tunable bandpass filter based on volume holographic gratings. It delivers the highest signal throughput in the industry and is also unique in that it combines very high optical density (> OD6) and outstanding out-of-band rejection with wide tunability. A single filter can be tuned from 400 nm to 1000 nm (VIS) or 1000 nm to 2300 nm (SWIR), with bandwidths (FWHM) of <2.5 nm and <5 nm respectively.
