Gas industry gets better control with imaging

Available now from Flir Advanced Thermal Solutions, the Flir GF320 is an optical gas imaging camera designed to help the oil and gas industry better control hydrocarbon emissions. The Flir GF320 Optical Gas Imaging camera is a real-time infrared camera designed for use in harsh industrial environments. The Flir GF320 takes advantage of a state-of-the-art focal plane array detector and optical systems that are tuned to very narrow spectral infrared ranges. This enables the camera to image infrared energy absorbed by hydrocarbon gas leaks. Images are processed and enhanced by the Flir High Sensitivity Mode feature to clearly show the presence of gases against stationary backgrounds. Gases that are detectable by the Flir GF320 camera appear on screen as smoke plumes.

Deep cooled focal plane offers NIR and SWIR imaging

Princeton Instruments has released its PIoNIR:640 camera that uses a deep-cooled indium gallium arsenide (InGaAs) focal plane array. The PIoNIR is designed for use in low-light near infrared (NIR) or shortwave infrared (SWIR) imaging and spectroscopy applications that require high sensitivity from 0.9µm to 1.7µm. PIoNIR applications range from nanotube fluorescence imaging to photovoltaic (PV) inspection.

Panasonic points to gesture control future

After seven years of extensive research and development, Panasonic Electric Works has announced its D-IMager 3D image sensor. The D-IMager uses near-infrared LEDs to emit light into a given area, which is reflected by objects and detected by a specially designed

Previous InGaAs cameras required liquid nitrogen to achieve deep cooling but vacuum technology developed at Princeton means the PIoNIR:640 can reach minus 90°C using thermoelectric cooling. The PIoNIR:640 uses a 640 x 512 InGaAs array with a peak quantum efficiency greater than 80 per cent with the thermoelectric cooling. It also has low-noise readout electronics to deliver the highest possible sensitivity.

charge-coupled device (CCD). When an object draws nearer or moves away, the delay between when the light is emitted and detected varies. By comparing such image data on a pixel-by- pixel basis, the D-IMager ascertains changes in distance precisely and in real time. This is known as the time-of-flight principle. Processing such 3D data and sensing

motion accurately makes the D-IMager perfect for a wide range of applications, from gesture- controlled digital games to remote control to building security. Panasonic’s patented background light suppression allows the D-IMager to be used even under strong ambient light conditions.

Accessories Kjellberg Systems get new Centricut consumables

Manufacturer of advanced metal cutting systems Hypertherm has announced the launch of an expanded line of Centricut brand consumables for Kjellberg systems. The new consumables are designed for high amperage stainless steel cutting using Kjellberg’s FineFocus 800, FineFocus 800 Plus, FineFocus 900, PA-S70, or PA-S75 systems. They include features that eliminate leaking compared to the OEM version and better cooling technology in the form of Hypertherm’s patented CoolFlow nozzle. This guarantees longer consumable life, enabling customers to

lower their operating costs without sacrificing cut quality or productivity.

36 ELECTRO OPTICS l FEBRUARY 2012 Phoenix Photonics announces 2μm fibre coupler

UK-based fibre optics specialist Phoenix Photonics has introduced 2μm fibre couplers. With growing demands for products in the 2000nm range, Phoenix Photonics has addressed the market by extending the operational wavelength of its current selection of all-fibre based components and introducing 2μm couplers available in 1x2, 2x2, tap, and cascaded configurations. The company’s proprietary in-house technology facilitates the step to offer components built on single mode fibre specifically designed for optimised operation in the 2000nm wavelength band.
