ULIS facility

Ulis logo

Our uncooled infrared detectors are manufactured by our sister company, ULIS, located outside Grenoble, France.

ULIS is a high-volume manufacturer of infrared detectors that are used in products designed for a diverse range of imaging applications including: building energy audits, thermography, security and surveillance, night vision driving, firefighting and military. ULIS has become a world leader in the production of microbolometer detectors based on amorphous silicon technology, an easy and reliable semiconductor material to manufacture. The ULIS microbolometers are now available in a range of form factors, from small to large, and are recognized because of their excellent performance while maintaining low weight and low power consumption. ULIS, a subsidiary of Sofradir and GE Equity, is located in Veurey-Voroize, near Grenoble, France and employs 120 people.

Key to the impressive advances in the design and manufacture of bolometer detectors is the long-term agreement that exists between ULIS and LETI (Laboratoire Infrarouge of the Electronics and Information Technology Laboratory, a renowned French Research and Development Center) which continues to bring technological improvements as a result of ongoing significant research. Below are some recent technical papers indicative of the quality and magnitude of the research being performed.

 

Recent ULIS Research Papers
High-performance uncooled amorphous silicon VGA and XGA IRFPA with 17μm pixel-pitch
Authors: J. L. Tissot, S. Tinnes, A. Durand, et al. Published 27 October 2010
ULIS and CEA/LETI have a great deal of accumulated expertise on amorphous silicon uncooled microbolometers with 45μm, 35μm, 25μm and now 17µm pixel pitch. Recent innovations developed on the 25μm pixel-pitch ROIC have been incorporated into 17µm pitch models including detector configuration by serial link, low power consumption, wide electrical dynamic range. The new detectors deliver remarkably high spatial resolution while keeping the small thermal time constant. The reduction of the pixel-pitch turns the TEC-less VGA array into a product well adapted for high resolution and compact systems and the XGA a product well adapted for high resolution imaging systems. High electro-optical performances have been demonstrated with NETD < 50mK.
High-performance uncooled amorphous silicon TEC less XGA IRFPA with 17μm pixel-pitch
Authors: C. Trouilleau, B. Fièque, S. Noblet, et al. Published 6 May 2009
A 1024x768 (XGA) IRFPA has been developed with 17μm pixel-pitch to address high end, high performance applications. This detector features: very high image resolution, two video outputs, low power consumption, wide electrical dynamic range, configurable by serial link. The reduction of the pixel-pitch turns this XGA array into a product well adapted for high resolution yet compact systems with excellent NETD coupled with wide thermal dynamic range as well as the outstanding uniformity and high pixel operability, achieved thanks to the use of highly stable amorphous silicon technology coupled with the ROIC design.
Uncooled amorphous silicon IRFPA for high performance and high volume applications
Authors: D. Pochic, A. Durand, J. L. Tissot, et al. Published 23 September 2009
Uncooled infrared technology has given rise to the opportunity for new applications for uncooled detectors including large volume markets. Compared to other infrared detector technologies, uncooled detectors offer many interesting advantages including high reliability and lower cost while delivering a level of performance that is sufficient for many applications. The development of amorphous silicon detectors for high volume applications is described. In addition, several design features are described that enable easier system development and reduced non-recurring costs. The appropriateness of different detector packages (metallic and ceramic) are described which depend on the application environment and the production volume.
VGA 17 μm development for compact, low-power systems
Authors: A. Durand, J.L. Tissot, P. Robert, et al. Published 20 May 2011
A new VGA 640x480 uncooled microbolometer IRFPA is described based on amorphous silicon technology with 17 μm pixel-pitch. This detector keeps all the innovations developed on the 25 μm pixel-pitch ROIC delivering high spatial resolution. The pixel-pitch reduction turns this TEC-less VGA array into a product well adapted for high resolution and compact systems. Electro-optical performance is presented as well as recent performance improvements. The tradeoff between NETD and wide thermal dynamic range is described, as well as the high characteristics of uniformity and pixel operability, achieved thanks to the mastering of amorphous silicon technology coupled with the ROIC design. Solar exposure is also taken into account and shows that ULIS amorphous silicon is perfectly well suited to sustain high intensity exposure.
