s4250 VNIR Hyperspectral Camera, in a nutshell
The VNIR 4250 is a non-contact hyperspectral camera covering the visible and near-infrared range from 400 nm to 1,000 nm. The 4250 weighs a scant 1.25 kg and measures only 198 mm x 81 mm x 78 mm. It is easily deployed in the field or inside a 24×7 production or inspective environment. Spectral resolution for the 4250 is 4 nm (FWHM) across 300 spectral bands.

The 4250 VNIR system represents the next generation of intelligent hyperspectral imagers. Based on front-staring Fabry Perot technology, the 4250 includes hardware and software required to support a broad range of hyperspectral imaging applications. Also, a tunable filter that sequentially selects spectral bands is placed in front of the sensor and generates the hyper-cube by collecting complete images at each spectral band-pass.
Additionally, the 4250 hyperspectral camera captures a complete high-spatial-resolution image data-cube across the visible to near infrared spectral range at 4 nm resolution in seconds, but can also be programmed to scan a subset of bands. This subset can be dynamically controlled based on the application and object to be imaged. Thanks to its design, the HinaLea 4250 offers high spectral and spatial resolution without the image uniformity challenges that line-scanning hyperspectral and patterned filter snapshot multi-spectral imagers present. In addition, HinaLea has developed its hyperspectral technology to be small, lightweight, and affordable for straightforward deployment in a lab setting, in a production environment, or in the field.
The presence of pathogenic microorganisms such as salmonella, listeria and E. coli in foods is a major threat to consumer safety and the food industry at large. Moreover, the failure to detect these pathogens can result in severe outbreaks of food-borne illness. The economic burden of food-borne pathogens is over $100 billion annually and results in the death of over four hundred thousand people worldwide each year. Current methods for detection are costly, involve complicated sample preparation and require days to yield results thereby increasing the severity of outbreaks.
Hinalea Imaging has developed a new means of rapid, reliable pathogen detection. Specifically, the self-contained system combines hyperspectral imaging, microscopy and deep machine learning which includes automated sample loading and detection.
Collaboration with the USDA has demonstrated rapid identification of pathogens in under 4 hours, thereby significantly reducing time to diagnosis and respond with a pathway to detection times of under an hour. This is revolutionary and changes pathogen detection and response from a laborious and time-consuming lab process to a user-friendly point-of-care solution.
Conventional machine vision systems are largely ineffective for the stringent evaluation of food and agricultural products. Commonly used machine vision systems utilize color video cameras with RGB filters that seek to replicate the imaging functionality of the human eye. For many of the required functions, this level of performance is inadequate.
Hyperspectral Imaging is a next generation imaging technology. It can be used as an augmentation or replacement to existing machine vision systems. Hyperspectral imaging provides high spectral and spatial resolution to enable comprehensive and data rich inspection of foods and other products. Additionally, Hyperspectral imaging can be extended into the UV or IR range providing details on chemical and structural composition not discernible in the visible spectrum.
It also provides added spectral information in a broad array of food safety and quality areas, including1:
- Detecting harmful foreign objects like plastics, wood, stones, metals and glass ;
- Identifying mechanical damage like bruising and abrasion ;
- Measuring food quality through attributes like ripeness, decay, freshness and ingredient homogeneity.
With global population set to hit 9 billion, the demand for food and water continues to grow. This heightened demand is going to put increasing pressure on the agriculture industry to improve crop yield and farm productivity. This need comes to an industry already stressed by farm economics and one that is struggling to manage the impact of climate change. As a result, precision agriculture is a potential solution for the agriculture industry.
PA is a farming management technique based on measuring and responding to the inter and intra-field variability in crops. As such, precision agriculture couples new technology with traditional farming techniques so that farmers can do more with less. Hinalea Imaging offers intelligent hyperspectral imaging solutions that can aid with the process of precision agriculture. Hinalea’s solutions couple state of the art imaging hardware with custom machine learning algorithms to solve specific farming problems.
Additionally, hyperspectral imaging provides added spectral information. Farmers use this information for an array of precision agriculture applications:
- Plant health & hydration
- Weed mapping
- Disease detection
- Optimizing harvesting
Industrial & defense
In addition to our work optimizing and safeguarding food supply chains, Hinalea works with customers to solve their problems across a range of industrial & remote sensing applications. In each of these applications, the customer problem we are solving is different. For example, current projects include:
- Aerial surveillance for threat detection
- Identification of chemical degradation of pipes
- QA of electrical components and displays
- Inspection of packaging
- Classification of raw materialsIn each of these use cases, Hinalea has been able to configure its imaging platform to address our specific customer requirements. The flexible form factor allows Hinalea to develop solutions for the specific environments of interest:
- UAV mounted SWIR imager capable of real-time imaging & classification
- Imager mounted on crawler for inspection of pipes in environmentally hazardous areas
- Integrated In-line quality assurance system for product grading
- Stand-alone, end of line quality assurance system for quality sampling
