Hyperspectral cameras combine imaging and spectroscopy. Instead of recording only a grayscale or color image, a hyperspectral camera captures spatial information and spectral information together, producing a data cube with two image dimensions and one wavelength dimension. This allows engineers and researchers to identify materials, measure subtle spectral differences, and classify objects based on optical signatures.
Pembroke Instruments supplies hyperspectral imaging systems, SWIR cameras, spectrometers, and technical support for scientific, industrial, semiconductor, machine vision, and material-identification applications.
A conventional camera measures intensity in broad bands. A hyperspectral camera measures intensity across many narrow wavelength bands. The resulting dataset is often called a hyperspectral data cube: two dimensions describe the image plane and the third dimension describes wavelength.
Every location in the image can be analyzed as a spectrum. This is why hyperspectral imaging is useful for material identification, coating inspection, moisture analysis, mineral mapping, semiconductor inspection, agriculture, biomedical research, and other applications where color or grayscale contrast is not enough.

Hyperspectral data cube: a spectrum is measured at each image pixel.
A hyperspectral imaging system usually includes illumination or emitted light from the scene, imaging optics, a spectral separation method, a detector, and software for calibration and analysis. The optical architecture determines whether the camera collects the cube by scanning or by acquiring it in a snapshot.
The sample reflects, transmits, absorbs, fluoresces, or emits light depending on its material properties and the illumination conditions.
Optics separate light into wavelength bands so the system can measure spectral signatures instead of only brightness or color.
Calibration and analysis software converts raw data into spectra, maps, classifications, and material-identification results.
Pushbroom hyperspectral cameras, also called line-scan hyperspectral cameras, collect one spatial line at a time. For each line, the camera records spectral information. The second spatial dimension is built as the object, conveyor, stage, drone, or camera moves.
Pushbroom systems are often preferred when the scene can move in a controlled way, such as conveyor inspection, scanning stages, drone mapping, laboratory measurement, and industrial line-scan applications.
See pushbroom hyperspectral system options or explore related SWIR imaging applications.
Pushbroom acquisition: a line is scanned repeatedly as the sample moves.
Snapshot hyperspectral cameras capture spatial and spectral information without scanning the scene line by line. Depending on the design, they may use filters, tiled spectral pixels, image mapping, computed reconstruction, or other architectures to collect spectral information in a single exposure or rapid acquisition sequence.
Snapshot acquisition: spatial and spectral information are captured without line scanning.
Snapshot hyperspectral systems are useful when the scene changes quickly, when scanning motion is difficult, or when a compact acquisition workflow is important.

The best architecture depends on the application. Pushbroom systems are generally strong for controlled scanning and high-quality spectral data. Snapshot systems are strong for dynamic scenes and fast acquisition where scanning is not practical.
| Decision Point | Pushbroom / Line-Scan Hyperspectral Camera | Snapshot Hyperspectral Camera |
|---|---|---|
| Acquisition method | Captures one spatial line plus spectrum, then builds the image through motion. | Captures the scene without line-by-line scanning. |
| Best application fit | Conveyors, scanning stages, laboratory mapping, drone mapping, industrial inline inspection. | Moving scenes, biomedical research, field imaging, compact integration, rapid events. |
| Motion requirement | Requires controlled motion or scanning. | Does not require line-scan motion. |
| Common advantage | High-quality spectral data and controlled acquisition geometry. | Fast acquisition and reduced motion artifacts for dynamic scenes. |
| Common trade-off | Motion synchronization and scanning setup are important. | May trade spatial or spectral sampling for speed and compactness. |

Pembroke Instruments offers hyperspectral and multispectral imaging platforms for snapshot imaging, pushbroom scanning, line-scan inspection, laboratory measurement, OEM integration, and application-specific material analysis. The product page includes visible, NIR, SWIR, and extended SWIR options for scientific and industrial users.
Extended-SWIR hyperspectral imaging option for material analysis, research imaging, semiconductor-related inspection, and applications requiring response beyond standard InGaAs SWIR cameras.
SWIR hyperspectral imaging platforms support wavelength-dependent contrast from approximately 900 to 1700 nm for material identification, inspection, and scientific workflows.
Pushbroom and line-scan hyperspectral configurations are used for conveyor inspection, scanning stages, laboratory measurement, and high-quality spectral data cube acquisition.
Hyperspectral imaging is valuable when spectral contrast provides information that standard visible, NIR, SWIR, or thermal cameras cannot provide alone. Pembroke Instruments helps match wavelength range, camera architecture, optics, illumination, and software to the measurement objective.

Explore SWIR cameras →The best hyperspectral imaging system depends on the material, wavelength range, scene motion, spatial resolution, spectral resolution, illumination, optics, software, and integration requirements. A camera that is excellent for drone imaging may not be the best choice for laboratory material analysis or conveyor inspection.
Multispectral imaging usually captures a smaller number of broader bands. Hyperspectral imaging captures many narrower bands, creating a more detailed spectrum at each pixel.
Neither is universally better. Pushbroom is often preferred for controlled scanning and high-quality spectral data. Snapshot is often preferred for moving scenes or applications where scanning is not practical.
SWIR hyperspectral imaging is useful when materials show important spectral contrast in the short-wave infrared, including polymers, minerals, coatings, moisture, semiconductors, and certain industrial materials.
