• Spectral range & resolution — Must cover the wavelengths relevant to your application (e.g., VIS, NIR, SWIR) and have fine spectral resolution (e.g., < 1-2 nm) for accurate material discrimination. For example, HORIBA’s imaging spectrometers support resolutions beyond 1 nm.

  • Spatial imaging & detector type — Beyond spectrum of a point, you’ll often want area‐scan or line‐scan capability so you get a full image + spectrum (a “spectral cube”) in industrial inspection settings.

  • Throughput & integration readiness — Look for high frame rates, robust mounting / optical interfaces (C-mount, area scan, line scan) and data interfaces (USB, Ethernet) so it fits into production or inline inspection. For example, spectral imagers can support 41 Hz full frame or higher with ROI.

  • Industrial ruggedness & support — Devices must handle real factory/industrial environments (vibration, dust, thermal drift) and come with software/SDKs for integration. For instance, hyperspectral systems marketed for “industrial inspection” mention IP-rated builds.

  • Software & data handling — Spectral imaging generates huge data sets. The vendor should provide or support software for data cube handling, classification, export, real-time analysis. The ability to interface with PLCs or factory systems is a plus.

  • Total cost & serviceability — These systems can be expensive and critical: make sure you check not only the purchase price but shipping to your location (e.g., Pakistan), calibration and service support, spare parts, and possible import duties.
