Why this service
What HSI can help you understand
Hyperspectral Imaging is selected when the project needs defensible information on reflectance, transmittance, emission, or loss versus wavelength, spectral classes and spatial distribution, or…
Spectral classes and spatial distribution
push-broom or microscope mapping
Absorption features, defects, or fibre attenuation
insertion-loss, attenuation, or emission spectral testing
Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.

Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Spectral data cube or fibre spectrum reported with the agreed units, sample reference and measurement conditions.
Classified or feature maps supplied in a labelled format suitable for direct sample or condition comparison.
Calibrated reflectance/transmission and selected wavelength plots provided with the processing basis and quality checks agreed during technical review.
Method-specific images included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Film / coating | Provide the coated substrate or a flat film with the test surface and coating side clearly marked. | State the substrate, nominal thickness and whether sectioning or mounting is permitted. |
| Fibre / textile | Provide clean, dry fibres or a representative textile section in protective packaging. | State the fibre type, orientation and whether cutting, bundling or mounting is acceptable. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What should I send for Hyperspectral Imaging?
Provide film / coating, fibre / textile, liquid / solution, device / assembly as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which analysis option should I choose?
The final method, preparation and reporting scope are confirmed after the sample and project objective have been reviewed.
How long will the test take?
Typical turnaround is 5 working days after sample acceptance and method confirmation.
What can limit the result?
Illumination, focus, scattering, and calibration transfer affect comparability. Spectral classes require representative references or validated models.
