Three new <a href=uncooled IR detectors from ULIS" ALIGN="RIGHT">

ULIS (Sofradir group), a developer of uncooled IR detectors, announced its 25?m family of amorphous silicon IR detectors, including the UL 02 15 2, UL 04 17 1 and UL 03 19 1.

Designed for use in thermography and industrial applications, the UL 02 15 2 features a 160 x 120 pixel array format, thermal time constant of less than 7ms, CMOS read out circuit, 70 percent area fill factor, and an 8-14?m spectral response. Rated for operation between -40C to 60C, this IR detector has a typical operability of greater than 99.9 percent with a high uniform response. It weighs less than 5g and measures 16.6-by-16.5-by-4.2.

The UL 04 17 1 features a 640 x 480 pixel array format and a signal response of 7mV/K. With the same features as the first model, this device possesses considerably higher performances. The operating temperature range with TEC and focal plane at 30C vary from -30C to 60C, whereas operating temperatures range from - 40C to 85C is possible for other focal plane temperature. Typical operability and standard deviation are identical to the UL 02 15 2. The focal plane temperature is stabilized by an integrated TEC. The UL 04 17 1 weighs less than 30g and measures 32-by-23.5-by-7.4mm (excluding pins).

The last silicon IR detector is the UL 03 19 1. This product delivers a 384 x 288 pixel array format and windowing capability, with its performances identical to the UL 04 17 1. The UL 03 19 1 has an analog and digital output, and is intended for applications in predictive maintenance, industrial process control, medical imaging, security and enhanced driver night vision.
