Photon etc V-EOS Widefield Hyperspectral Imager

The V-EOS Hyperspectral Imager from Photon etc offers complete information on the target with complete resolution images at any wavelength in the range 400 to 1000 nm. Photon etc’s V-EOS will completely change how you view spectral analysis.

Key Features

The key features of V-EOS widefield hyperspectral imager are:

  • Continuously tunable
  • Control and analysis software
  • Non-dispersive technology
  • High-performance CCD
  • Motorized focus

Applications

The applications of the V-EOS are:

  • Mining, oil and gas operations: The Photonic Knowledge’s Core Mapper offers an array of monochromatic images at user-specified wavelengths, offering instant in situ mineral identification. Spatial resolution is then 900 times better, and field of view is 1666 times wider than any presently available handheld mineral spectrometer. It can provide fast mineralogy fields mapping services, as high as 1500 drill core meters per day with a single imager.

  • Dermatology: This method involves acquiring then analyzing a hyper-spectral data cube using adjustable wavelength spacing or image sizing. The patented non-scanning technology of Photon etc provides images with an unmatched combined spectral/spatial resolution. This helps in mapping oxygen, hemoglobin, deoxyhemoglobin and melanin in tissues, thus facilitating diagnosis and monitoring of treatments, including in the context of dermatological clinical studies.

  • Environment and agriculture: There are a large number of potential applications for hyperspectral imaging in the fields of environment and agriculture. In all cases, the identification of any type of molecule is done by analyzing its characteristic spectrum. The range of instruments offer unique solutions whether it is for the analysis of contaminants in soils, the sugar or water content of fruits or fat and protein levels in liquids.
