Baldur hyperspectral line scanner With the Baldur line of industrial cameras, Norsk Elektro Optikk presents a newly designed hyperspectral line scanner, available from Sphere Optics. All Baldur cameras are based on Nyquist spectral sampling, meaning the spectral point spread function is sampled by two pixels on the detector to give a spectral resolution of two spectral bands. At the same time, Baldur cameras capture four times more light than classic systems, which make them a perfect fit for industrial applications that usually require a fast acquisition rate. Additionally, the spatial resolution is better than 1.7 pixels, yielding sharp images. Te HySpex Baldur covers the spectral


range from 400 to 1,000nm and 950 to 2,500nm in several configurations with selectable ranges. All cameras in the same wavelength range have the same centre wavelengths, making them interchangeable. Tey are supplied with traceable calibration standards to NIST and PTB. HySpex cameras – Baldur as well as Classic and Mjolnir – are delivered with a high-end SDK and library that makes it simple to integrate the hardware into third- party software. http://neo.no and www.sphereoptics.de


Camera with quad-core processor Vision Components premiered the first prototype of its latest generation of embedded vision systems at the recent Embedded Vision Europe show in Stuttgart, Germany. Te onboard quad-core processor, Qualcomm’s Snapdragon 410, is clocked at 1.2GHz. Te board camera features a gigabit Ethernet interface, 12 GPIOs, 1GB RAM, and 16GB flash memory. Two optional add-on boards provide the embedded system with an SD card slot and more interfaces: serial interface, I²C, RS232, DSI, RJ45 Ethernet adapter, and power interface. Vision Components integrates high-end CMOS


sensors, starting with Sony Pregius IMX 296, which features a resolution of 1,440 x 1,080 pixels and 60fps frame rate. More image sensors will follow. Vision Components guarantees long-term


Illumination


Hyperspectral lighting range Effilux has introduced a hyperspectral imaging lighting range. Te device was created from an LED developed by CCS that offers a tuneable continuous spectrum from 400 to 900nm. Te light source can be integrated easily into a wide variety of lighting

for machine vision and scientific imaging. CCS’s tuneable single LED


illumination source overcomes the limitations of halogen – lifetime, heat dissipation, stability, and environmental issues – and multiple narrowband LED-based hyperspectral lighting solutions (spatial and spectral uniformity,


continuous spectrum, cost issues). With Effilux’s expertise in optics


and CCS’s LEDs, this point source design provides exceptional spatial and spectral uniformity without wavelength-dependent angular absorption effects. Te hyperspectral LED can be strobed if required and multiple LEDs can be mounted on a single PCB if increased output


intensity is needed for high-power applications. Te spectrum can also be tuned in the available spectral range tailor the light output to specific requirements, making it ideal for multispectral imaging. Te device is available in form


factors including bar, ring, backlight, line light, projector and others. www.effilux.com/hyperspectral

Hera hyperspectral camera Te Italian company Nireos, an official spin- off from the Politecnico di Milano University, has introduced a hyperspectral camera called Hera. Each pixel in Hera’s sensor device is able to capture a continuous spectrum between 400 and 1,000nm in a few seconds to create a hyperspectral data cube. Te camera measures 15.7 x 15.5 x 11cm. Hera is based on Fourier-transform


technology, which operates without filters or gratings. Instead, the camera employs an ultra- stable interferometer with a 1cm clear aperture, which gives straightforward acquisition of images even in challenging conditions, such as low light levels.


Te camera has 1nm resolution at 400nm


wavelength, making it able to distinguish different materials in the visible region with excellent accuracy. Lower spectral resolution is possible to make faster measurements. Te camera is supplied with user-friendly


software. Te hyperspectral camera is suitable for researchers performing fluorescence imaging, cultural heritage conservation and other low- light applications. www.nireos.com


WiDy Sens 640 OEM To address the demand for integrating SWIR cameras into custom systems, particularly small and lightweight gimbals, NIT has released a split version of its flagship WiDy Sens camera: WiDy SenS 640 OEM. Te camera version integrates the NIT


InGaAs sensor NSC1601, a 640 x 512-pixel sensor with 15µm pixels. Te sensor operates in the 900 to 1,700nm range at a maximum full frame rate of 230fps, with sub-frame rates possible up to 10kHz. Both electronics and sensor are linked


by a flex cable available at different lengths. Tis assembly allows integrators to separate processing electronics from the sensor in order to mount the sensor easily into the system. All the features of the WiDy Sens camera


availability for its cameras. Tis makes the freely programmable embedded systems with a Linux operating system ideal for any OEM design and for industrial serial production in particular. www.vision-components.com


series are preserved, such as fast gating capability, switchable linear-logarithmic mode, and low noise performance. Te cameras are available with USB 3.0 or Camera Link interface. www.new-imaging-technologies.com
