Hyperspectral filter technology
for mobile devices

Our spectral sensors leverage our disrupting technology to meet mobile and consumer device requirements, enabling advanced user-environment interfacing, big data analysis, image fusion, and new applications such as skin health, smart gardening, secure authentication and accurate color photography.

Wafer-scale filter technology

Spectricity’s patented wafer-scale hyperspectral filter technology is the fruit of over ten years of R&D, and successful deployment in low-volume production and applications. Unlike other solutions, Spectricity’s filters do not require complex and bulky optics or packaging, slow scanning or sophisticated calibration.

Thanks to our complete CMOS integration, our sensors can be truly miniaturized; following the principles of standard image sensors, optics, packaging, system requirements and supply chains. Our sensors are manufactured in high volumes at our mass-production CMOS foundry.

Conventional RGB filters

Conventional RGB filters are standard in consumer image sensors. These solutions provide limited spectral resolution (e.g. 100 nm), and focus on the visible range of the spectrum.

Spectricity filter technology

Spectricity leverages a patented technology to integrate spectral filters at pixel level on image sensors. This provides a much higher spectral resolution (e.g. 5-30 nm), while retaining the advantages of high-volume CMOS manufacturing processes.

Typical RGB specifications

Spectral range: 400-700 nm

Number of filters: 3

Typical Spectricity specifications

Spectral range: 350-1000 nm

Number of filters: up to >100

Trading spectral for spatial resolution

Using integrated and versatile spectral filter technology, low-cost and miniaturized spectral sensing is possible, from spectrometers with high spectral resolution, to spectral imagers with high spatial resolution.

We expand the traditional paradigm of color imaging to spectral sensing. Our technology makes it possible to trade spectral for spatial resolution: a traditional RGB sensor uses 3 color filters in a Bayer pattern. A spectral sensor could use more filters (e.g. 9 or 16) in a mosaic pattern. A spectrometer may use 128 channels across a sensor.

Plug and play sensing systems

Spectricity spectral sensing systems are easy to integrate into your applications. You don’t need to hold a PhD to¬†integrate our sensors.

We achieve this by leveraging our deep technical understanding of sensors, filters and algorithms. Our sensor systems are calibrated and provide clean, ground truth, part-to-part repeatable spectra.

Our solutions come with applicable and optimised optics, a simple interface, a cross-platform API, and initial application algorithms to allow for quick validation of the technology in your applications.

Image fusion and more robust computer vision algorithms

Apply the power of spectral sensing in your camera systems. Fuse spectral images and RGB images to create rich data in dynamic environments and enable advanced computer vision applications. Combine spatial features and spectral features, to increase the accuracy of the algorithms. Make your computer vision color-based algorithms robust in uncontrolled and complex user environments.
