Xenics InGaAs Detectors Go Into Orbit

The firm's indium gallium arsenide SWIR detectors were launched aboard the ESA satellite Proba-V to map crop and vegetation patterns across the face of the earth
European manufacturer Xenics has released a high-resolution line-scan detectors for demanding scientific and industrial applications.

On May 7th three of Xenics' new Xlin-1.7-3000 SWIR InGaAs detectors were launched aboard the ESA satellite Proba-V.

Besides delivering a high resolution, the new line-scan detector offers high line rates and low noise.

The Xlin-1.7-3000, a line-scan detector in InGaAs technology offers over 3,000 pixels of resolution. Xenics says this is the best specification of any such device on the market.

With its high sensitivity in the SWIR range (0.9 to 1.7 μm) the Xlin-1.7-3000 is suited for the Proba-V (vegetation) satellite mission orbiting at an altitude of 880 km. 

It reveals detailed long-term information on the changing crop and vegetation patterns of the planet and other vital parameters for preserving the biosphere.

Perfectly Suited for Space

The Xlin-1.7-3000 line-scan detector is qualified for space missions with 10 krad of ionising radiation while maintaining its specified performance. A full qualification campaign as prescribed by ESA was carried out, covering harsh environmental, radiation and life test conditions.

Three of the new detectors are currently mounted on the Proba-V satellite, ready for launch with the new ESA VEGA launcher from Kourou, French Guyana. Right after the launch, the detectors will start delivering valuable earth environmental information in the SWIR range over a swath of 2,200 km with a centre resolution of just 100 m.

The Xlin-1.7-3000 consists of three individual InGaAs sub-arrays of 1,024 square pixels (25 x 25 μm) each. They are mechanically butted on a gold-coated boat and mounted on an alumina substrate, together with three individual readout-ICs (ROIC).

The overlap of 20 pixels enables perfect stitching of three individual images to a continuous line of 3,020 pixels over a length of 75.5 mm. The detector is assembled in a custom hermetically sealed 72-pin package with anti-reflective coated window. It is optionally also available in an open package.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
