Cubert ULTRIS S-Line Hyperspectral Cameras

Small, fast and affordable hyperspectral cameras from Cubert

Video-rate hyperspectral imaging offers unprecedented capabilities to capture and analyse vast amounts of spectral data in real-time. With the ability to record and process images across multiple narrow spectral bands simultaneously, video-rate hyperspectral imaging has the potential to transform industries such as agriculture, machine vision, medical imaging, and surveillance. By providing high-resolution spectral information, it allows for improved accuracy and reliability in object recognition and classification, enabling automated decision-making systems that can enhance productivity, efficiency, and safety. As such, the growing adoption of video-rate hyperspectral imaging is paving the way for a new era of intelligent machines that can see and interpret the world with greater precision and speed than ever before.

Cubert has dramatically reduced the size of their ULTRIS light field technology to create a video-rate hyperspectral camera based on a 5 Megapixel sensor that measures just 30 x 30 x 50mm and weighs only 120g. The ULTRIS 5 is a compact hyperspectral “snapshot” camera covering the spectral range from 450-850nm with a total of 51 spectral bands, and with frame rates of >15Hz. With a relay lens, the camera can even be mounted on more complex optical systems, such as microscopes, endoscopes or industrial inspection systems.

The ULTRIS S5 features the same footprint and price as a standard industrial imaging camera, but it delivers an incredible spectral discrimination in comparison. This enables new applications in food quality and safety, medical imaging and remote sensing alike.

The ULTRIS S5 is the most versatile addition to Cubert’s family of light field hyperspectral cameras. It is small enough to fit into any industrial process system, powerful enough to fill medical imaging requirements and fast enough to record complete non-scanning snapshot data cubes at 15Hz.

Alternative configurations of the ULTRIS S5 are available for endoscope and microscope use, and custom wavelength ranges can be provided upon request.

Key Features of Cubert ULTRIS SR5

Plug and play: the ULTRIS SR5 brings an optical adapter enabling hyperspectral medical imaging. Cubert’s ULTRIS snapshot cameras are designed to allow real-time analysis of time-critical processes, making them perfectly suited for any biomedical application. The relay lens adapter connects the imaging spectrometer to your medical device expertly and quickly. The new adapter is compatible with any C-Mount objective, enabling video spectroscopy in real-time. Any lens, including macro optics or fish eye lenses, can instantly be mounted onto the camera. The camera can even be mounted on more complex optical systems, such as microscopes, endoscopes or even industrial inspection systems.

The ULTRIS SR5 is supplied with powerful software and an SDK for applications in microscopy and endoscopy. 

The ULTRIS SR5 is a huge step forward in bringing hyperspectral light field technology to biomedical applications. It is designed to quickly provide critical information. Cubert’s powerful HSI software CUVIS takes Raw Data, Reflectance and even Radiance in real-time. Customized plug-ins and classification solutions can be directly applied to the live view. The powerful SDK allows for smooth system integration. Originally developed in C, the SDK is now available with wrappers for C++ and Python.

Key Features of Cubert ULTRIS H5

The ULTRIS H5 is the 10 GigE version of our standard ULTRIS 5. The camera properties are the same, featuring a resolution of 290 x 275 pixels and 51 spectral bands covering 450-850nm. Equipped with a 10 Gigabit Ethernet port, the integrated Sony IMX250 sensor can unleash its full potential and can record at up to 75 Hz while retaining the typical 12 bit depth, which is often needed for hyperspectral imaging applications.
