Core Scanner | HySpex Solutions

The HySpex Geological Workstation incorporates HySpex VNIR and SWIR cameras, as well as Telops MWIR and LWIR cameras for scientific-grade hyperspectral imagery. The system is designed to be easy to use, allowing you full control over your data, analysis, and results.

Real-time interpretation and visualization of the scanned core identifies areas of significance, such as alteration mineralization, highlighting sections requiring assay or geochemical sampling. The resulting mineralogic interpretation and logs can be exported in common formats and are easily included in other core logging software to enable a comprehensive understanding of the data. It also allows you to revisit and reevaluate your data as needed without incurring extra fees.

Though the workstation is optimized for core boxes, it can also handle drill chip boxes, loose samples, and rock mass.

¹ User-selectable by software, between 2cm (-1) (~3.2nm @ 4 microns) and 64 cm (-1) (~50nm @ 4microns) resolution is typically recommended for MWIR core scanning
‍² User-selectable by software, between 2cm (-1) (~20nm @ 10 microns) and 64 cm (-1) (~640nm @10 microns) resolution is typically recommended for LWIR core scanning.
³ User-selectable by software, between 28 and 896; 56 spectral bands is typically recommended forMWIR core scanning
⁴ User-selectable by software, between 10 and 320; 40 spectral bands is typically recommended forcore scanning
⁵ The dynamic range is expressed for a specific wavelength as the ratio between the maximumradiance the camera can handle and the minimum detectable change in spectral radiance at thatwavelength, which corresponds to a signal-to-noise ratio (SNR) of 1.
⁶ It’s possible to reduce the spectral resolution or increase the measurement time to achieve higherSNR.
⁷ For recommended operating parameters; faster measurement rate is also possible.
