Products Cameras – Thermal Imaging


For detecting refrigerant gas leaks Flir Advanced Thermal Solutions (ATS) has released the Flir GF304, an IR gas imaging camera capable of detecting refrigerant gas leaks without needing to shut down the refrigeration system. The camera can be used to reduce


revenue loss by pinpointing even small refrigerant gas leaks quickly and efficiently, and from a distance. The innovative camera also reduces inspection time by being able to scan a broad area rapidly without the need to interrupt the refrigeration process. The camera contains a cooled Quantum Well Infrared Photodetector (QWIP) and a cold band pass filter that allows it to visualise various refrigerant gases in the 8.0-8.6µm waveband. Using a proprietary High Sensitivity Mode (HSM) further enhances the sensitivity of the camera so that the smallest gas leaks can be detected. The HSM feature makes the inspection process easier, faster, and more accurate for utility engineers and camera operators.


In addition to finding gas leaks, the Flir GF304 can be used for undertaking maintenance inspections where a temperature reading is required. The camera visualises temperatures

Multispectral camera JAI has released the AD-130GE, a 2CCD multispectral camera offering high resolution and excellent light sensitivity. Like the existing AD-080 series, the AD-


130GE incorporates a dichroic prism to provide simultaneous capture of both colour and near- infrared (NIR) digital video on a single optical path for efficient multispectral inspection and analysis.


The AD-130GE provides 1.3 Megapixel resolution (1,296 x 966 pixels). It uses two precisely-aligned 1/3-inch Sony ICX447 CCDs and provides a frame rate of 31fps. Sensitivity to visible light is approximately 20 per cent greater than the previous AD-080 models, while NIR sensitivity is more than twice that of its predecessors. This leads to higher quality images under typical conditions. www.jai.com


Cooled CCD camera Allied Vision Technologies has expanded its Bigeye family of cooled CCD cameras with the Bigeye G-283B. The camera is equipped with a Sony ICX674 monochrome CCD-sensor chip with 2.8 Megapixel resolution offering outstanding quantum efficiency and dynamic range. The model was developed with a focus on high-quality images. It delivers up to 6fps at full resolution in 14-bit mode. Like all members of the


Bigeye family, this camera is fitted with a Peltier module, cooling the sensor down to -10°C. As a result, the Bigeye G-283 delivers a excellent signal-to-noise ratio even with long exposure times. The camera is ideal for industrial and scientific imaging applications, fluorescent microscopy, low-light imaging and non-destructive evaluation of photo-sensitive objects. The camera is the first Bigeye model to include an upgraded AVT interface module. The new Gigabit Ethernet interface offers improved functionality: its 20-pin serial MRD interface provides four inputs and four outputs and two

from -20°C to +500°C enabling inspection of high voltage, low voltage, mechanical and many other facilities found in refrigeration plant and equipment.


Ergonomically designed with a bright LCD and tiltable viewfinder, it is easy to scan areas of interest with the camera that are difficult to reach with conventional methods. A USB WiFi adapter enables wireless connection of the camera to smart phones or tablet PCs facilitating wireless transfer of images or remote control of the camera. The Flir GF304 comes either with a fixed 14.5° lens or with a fixed 24° lens as standard. www.flir.com


Goodrich has introduced the GA640C-15A shortwave infrared (SWIR) camera. With a volume less than one cubic inch, weighing only 26g without its lens, and consuming 1.5W, the camera is ideal for integration into handheld, helmet, or weapon-mounted surveillance devices and unmanned aircraft. The camera features 640 x 512 pixel resolution with a 15µm pitch.


The uncooled SWIR detector images in real time (30Hz), daylight to low light, through smoke, haze, and fog conditions. It operates without temperature stabilisation using non- uniformity corrections. The C-platform model operates from 0.9 to 1.7µm and the optional near infrared camera model extends the spectral response to include 0.7 to 1.7µm. The camera operates in a wide temperature range from -35°C to +71°C. www.goodrich.com


RS232 connectors are available additionally. Furthermore, the new module supports AVT’s multi-platform PvAPI software development kits (SDK), allowing for an easier and more efficient control of camera functions. Thanks to the AVT GigE SDK, the camera can be integrated easily in machine vision systems while the full GigE Vision compliance makes it possible to operate the camera with a large choice of third-party image processing libraries. www.alliedvisiontec.com
