Xenics XLIN-FC

Xenics, a developer and manufacturer of advanced infrared detectors, cameras and customized imaging solutions from the SWIR to the LWIR realm, once again return to San Francisco for the BiOS and Photonics West show.

Expect to learn more about the latest in-house developed XLIN-FC series, during the two events. The XLIN-FC detectors are ultra-high speed SWIR line scan detectors suitable for applications in machine vision and spectroscopy. 

Entering the finalists round in the SPIE PRISM Awards for the category “Detectors and Sensors”, the XLIN-FC series are the latest linescan SWIR InGaAs detectors from Xenics. Using flip-chip (FC) type hybridization, we offer two high speed detector types:

  • XLIN-FC R with rectangular pixels for spectroscopy applications, and

  • XLIN-FC SQ with square pixels for machine vision inspection applications.

The detectors operate in low illumination conditions thanks to a new high-sensitivity ROIC (read-out integrated circuit) developed in-house by Xenics. The InGaAs photodetectors also exhibit a high QE in the 900 to 1700 nm wavelength range.

The detectors come in different resolutions: 512, 1024 or 2048 pixels. Fast in-line inspection is guaranteed with the world-record line rate of up to 400 kHz, for all three resolutions.

Five gain settings are available to optimize performance (sensitivity and dynamic range) in a specific application. In highest gain mode, a very low read noise of 70 electrons can be achieved. The high dynamic range mode is characterized by a maximum signal-to-noise range of more than 3000.

XLIN-FC SQ (Square series)

For all three resolution versions, the XLIN-FC SQ consists of square pixels with a 12.5 µm pixel pitch and height. Even in the 2048 pixel version, the total array length does not exceed 25.6 mm.

The XLIN-FC SQ detectors are suitable for applications such as food sorting, waste recycling, remote sensing and (micro-) crack detection in solar cell wafers or ingots.

XLIN-FC R (Rectangular series)

The XLIN-FC R series consists of rectangular pixels with a pitch of 12.5 µm, and a pixel height for 250 µm, for all three resolution versions. Just like the XLIN-FC SQ, the total array length does not exceed 25.6 mm.

The XLIN-FC R is suitable for SWIR spectroscopy applications in general. Medical OCT (optical coherence tomography) systems can benefit greatly from high speed linescan detectors in the SWIR wavelength range. The high resolution of the XLIN-FC R extends the application area of OCT towards higher spatial resolution, providing detailed imaging for medical applications and analysis.

Xenics exhibits in booths 8512 (BiOS) and 1931 (Photonics West) at the Moscone Center.
