Photon etc. offers the V-EOS widefield hyperspectral camera, which gives complete information about the target with full resolution images at wavelengths ranging from 400 to 1000nm. With a patented design based on volume Bragg gratings, the V-EOSTM redefines spectral analysis and offers a range of monochromatic images at user-specified wavelengths.
Key Features
The main features of the V-EOS are:
- High-performance CCD
- Non-dispersive technology
- Continuously tunable
- Motorized focus
- Control and analysis software available
Applications
The applications of the V-EOS are:
-
Mining, oil and gas operations – Rapid mineral identification is performed by spectral signature analysis of improved underground exploration or by drill core characterization.
-
Dermatology – A software extension enables high precision mapping of the nature and extent of abnormal tissues, and also allows effective monitoring of the medication effects in clinical research
-
Environment and agriculture – Infrared spectroscopy helps in analyzing various components of the environment and helps fight different sources of pollution.
