Configurable LED illumination solution for hyperspectral SWIR applications

08-11-2021 | ProPhotonix | Lighting Technologies

ProPhotonix Limited has released its COBRA HyperSpec SWIR line light. This tunable SWIR line light provides for high-resolution, reliable imaging. It is fully customisable and can be configured for various applications, including textile recycling and quality control in the food industry.


“By using SWIR technology, even the most challenging materials can be illuminated. Many features or defects across several applications which are invisible to the human eye can be detected using wavelengths in the SWIR range,” commented Simon Stanley, director of technology at ProPhotonix. For example, in textile recycling, the COBRA HyperSpec SWIR configuration can be used to differentiate between artificial materials like polyester and plant-based materials such as cotton.


The SWIR LED line light is a customisable illumination platform allowing users to optimise the spectrum to maximise contrast, compensate for camera sensitivity and produce clearer, higher resolution images for improved accuracy and speed. Precise control of the light through its user-friendly GUI enables system designers to effortlessly fine-tune the performance of systems. Discrete control of each wavelength enables users to choose the optimum wavelength balancing and relative intensities specific to the application requirements. For high-speed image acquisition, the platform’s outstanding strobe capability can be configured to pulse all four strobe lines simultaneously or sequentially with a combined delay and response time of less than one 1μs. Also, it provides field adjustable optics enabling users to choose the optimum lens position for its application. The solution is modular and available in any length up to 6m.


Commenting on the new product, Simon said: ”Our launch of the SWIR COBRA HyperSpec LED Line Light gives companies more flexibility to test this new technology and better define their specification. This makes it an ideal evaluation product allowing us to partner with the customer to produce a tailored solution to meet their specification.”
