QWIP photodetector from IRnova detects several different gases

A 320 × 256 quantum well infrared photodetector (QWIP) sensor has its peak wavelength at 10.55 μm to meet requirements from customers developing leak detection systems for the greenhouse gas SF6 (sulfur hexafluoride) from power stations. The detector’s peak wavelength can be tailored
to detect several different gases.

PRESS RELEASE

IRnova launches a new QWIP (Quantum Well Infrared Photodetector) sensor for detection of the strong greenhouse gas SF6

The new 320x256 detector has its peak wave length at 10.55 μm to meet requirements from customers developing systems for detection of leakages of the strong greenhouse gas SF6 (sulfur hexafluoride) from power stations.

Many countries, e.g. China, are implementing regulations in order to minimize gas leakages affecting the global warming. Strong efforts are made by camera/system manufacturers all over the world to develop new systems able of detecting various hazardous gases.

“IRnova has the ability to provide efficient detector solutions for these applications, not only for SF6 detection. We do see a very interesting rapidly growing market for which we are keen to establish IRnova as a major supplier. The new detector adds up to IRnova’s broad portfolio of IR detector products and is in line with IRnova’s goal to increase the usage of QWIP detectors for industrial applications.” says Ulrika Nordén Lidberg, CEO at IRnova.

IRnova can tailor the peak wave length of the detector to meet requirements for detection of several different gases. These detectors can be used in gas and oil industry and for monitoring pipelines with stationary as well as airborne camera systems.

The new detector can be supplied as FPA (Focal Plane Array) as well as integrated into a DDCA (Detector Dewar Cooler Assembly). The detector needs to be cooled to below 60K.

Prototypes for evaluation and in-design can by supplied in the fourth quarter 2011 and volume shipments are planned for the second quarter 2012.
