Imec’s on-chip technology makes hyperspectral imaging robust, compact and mass-producible. This is how it works.
Hyperspectral imaging technology is designed to make images that reveal a maximum of spectral information for each pixel of the image.
Another way of looking at a hyperspectral image is as a set of image layers, each in another wavelength of the electromagnetic spectrum. The combination of those layers is called a hyperspectral data cube.

There are multiple hyperspectral imaging technologies. Each applies different techniques to filter the light and capture the image data. The key differentiators you need to keep an eye on are:
Selecting the required properties is a tradeoff, driven by the requirements of the application. If you know which spectral bands to look for, there’s no need to capture the full spectral range. Especially because a lower resolution will enable faster acquisition speeds and open new possibilities with hyperspectral video imaging.
Imec can assist you in tailoring its hyperspectral imaging technology to your application. For instance, why not use one of our high-resolution cameras to define which frequency bands are relevant for your needs? Afterwards, we can help you to build your dedicated filters or camera system.
Traditional hyperspectral imaging cameras contain a lot of precision optics to select and diffract the light. This makes them relatively heavy, expensive, slow and delicate – with a need for frequent recalibration.
Imec’s hyperspectral imaging technology takes a different approach. As a world-leading R&D hub in nanotechnology, we have developed a wafer-level CMOS process to integrate thin-film spectral filters directly on the pixels of the image sensor.
Our filters eliminate the complex optical camera design and can be deposited on a commercial CMOS imager, like the one in your smartphone or a model with scientific imaging capabilities.
The result is that our hyperspectral image sensors enable imaging systems that are:
This leads to the increased adoption of hyperspectral imaging in a range of applications.
Our unique on-chip hyperspectral imaging technology allows us to make different spectral filter patterns. Those fall into two categories:
This website offers you an overview of our ready-to-use evaluation kits, including remote support, and the easy-to-use HSI STUDIO, HSI MOSAIC and HSI SNAPSCAN software suites to make hyperspectral imaging accessible to anyone.
Of course, we can also develop custom hyperspectral image sensors, with your desired pattern lay-out, filter specification, imager chip, ... All the way up to the design of the complete camera system.
