Products Cameras
Drone for hyperspectral remote sensing Polytec has introduced a complete drone solution for hyperspectral remote sensing. The systems, from US manufacturer Headwall Photonics, are suitable for precision agriculture, environmental protection, forestry and surface mining. They are based on a professional multicopter with adapted gimbal for image stabilisation.
Bolt and Accel 25GigE cameras Emergent Vision Technologies (EVT) has added 25GigE cameras to its product line-up, now available from Framos. Both EVT’s Bolt and Accel 25GigE devices offer a 3.125MB/s frame rate. Until now, this speed was only attainable with four-channel CoaXPress. The new interface requires only a single fibre cable, compared to four cables for Quad CoaXPress. The use of SFP28 fibre cables, plus step-up transceivers, enables cable lengths of up to 10km to be used. Handling and integration are becoming easier and cost effective; the 25GigE interface offers superior capability with a great combination of speed and distance. EVT offers dedicated NIC card solutions to reduce CPU loading, and to manage video triggering and streaming. Data from the camera is processed directly on the NIC for smooth integration and operation of the 25GigE vision solution.
CPU processing remains under five per cent.
The new interface offers network support and synchronisation via the IEEE1588 standard, and is GigE Vision and GenICam compliant.

Integrated components also include a positioning sensor for flight parameter control, the VNIR or SWIR hyperspectral imaging sensor, and software for flight planning, post-processing and image correction, analysis and combination with geodata.
Depending on the application, the system
is fitted with a Nano-Hyperspec VNIR sensor for the visible and near-infrared wavelength range, or with a Micro-Hyperspec sensor for SWIR. An additional lidar module can be integrated as an option.
Parameters such as vegetation indices can be recorded, and other characteristics, for example plant disease or pests, can be identified using suitable models.

Model 4200 hyperspectral camera HinaLea Imaging has launched its Model 4200 wide-field hyperspectral camera. Features include lens options to match field of view, and working distance requirements for laboratory and industrial applications. The configurable system enables users in both research and industry to tailor the instrument to their needs. The Model 4200 is a front-staring band sequential
M12B cylindrical microscopy camera Pixelink has expanded its line of Sony IMX-based USB 3.0 microscopy cameras with a new 12 megapixel 4K ultra-high-definition model. The M12B cylindrical microscopy camera is based on the Sony Pregius IMX304 CMOS sensor. It is available in both colour and monochrome with a 1.1-inch lens format. The M12B delivers outstanding imagery in
dark field, differential interference contrast (DIC), polarised light and basic fluorescence. The camera can also be purchased with Pixelink µScope software, which offers image capture and analysis, annotation and measurement tools.

Sweep+ three-CMOS colour line scan JAI has added a three-CMOS prism colour line scan camera to its Sweep+ series. The SW-4000T- MCL features three custom CMOS line sensors with 4K (4,096 pixels) resolution, mounted on an optical prism assembly that splits the incoming light into red, green and blue wavebands. The camera gives 24-bit, non-interpolated RGB output at up to 67.7kHz, which is more than four times faster than previous 4K prism colour line scan cameras. To support its high-speed operation, the SW-4000T-MCL features three custom CMOS imagers with 7.5µm square pixels, offering high responsivity for the short exposure times needed at maximum line rates. In addition, each of the three CMOS sensors has two adjacent lines, making it possible for horizontal binning, vertical binning, or both. Furthermore, the sensor’s readout architecture combines the readout of two pixels through a single diffusion node to double the signal without increasing noise, enabling the binning process to increase sensitivity. The cameras have a built-in colour conversion

hyperspectral system, which can scan the whole VIS-NIR (400nm to 1,000nm) spectrum, with high spatial and spectral resolution. It can also be programmed to scan only a subset of bands, and this subset can be dynamically controlled based on the object being imaged. Scans can therefore be shorter, with generally smaller data sets, saving customers time and money.

capability that gives native HSI or CIEXYZ colour output, in addition to offering conversions from standard RGB to the sRGB or Adobe RGB colour spaces, or even to a user-defined custom RGB conversion matrix. For encoder connection, the SW-4000T-MCL features four separate input lines, plus built-in algorithms to support direct connection from up to two rotary encoders. It uses a GenICam and Gen-CP-compliant Camera Link interface with Mini Camera Link connectors to output line data. Base, medium, full or Deca configurations are supported.
