Xenics, Europe's leading developer and manufacturer of advanced infrared detectors, cameras and customized imaging solutions from the LWIR to the visible realm, introduces the third member of its high-resolution 'Xenics Core' Infrared OEM product family. The new Stirling-cooled XCO-640 MWIR module provides unprecedented stability and optical performance for perimeter surveillance, law enforcement and homeland security. At DSS 2015 Xenics exhibits in Booth 825.

Xenics presents its new Stirling-cooled XCO-640 midwave infrared core for long-range monitoring in highly demanding perimeter control, law enforcement and homeland security applications. The new OEM module is the third member of the 'Xenics Core' OEM product family. XCO-640 is based on a new platform with similar image processing features as the high-resolution OEM modules XSW-640 (shortwave IR) and XTM-640 (thermal imaging), which Xenics had introduced in January 2012.

The new XCO-640 long-range MWIR surveillance core shown at DSS 2015 offers a rugged setup with several 22x zoom lens options, fully controllable via Serial Protocol. Lenses with different focal lengths (15-330mm, 30-660mm or 37.5-825mm) can be used on the same MWIR imaging core. Also, Xenics provides on-board autofocus functionality. This way, large-area infrastructures, such as airports, can be monitored by a few pan-and-tilt cameras, simplifying the surveillance logistics.

Another unique feature of the XCO-640 core is that it can be operated with different sensor types, based on either MCT or InSb detector materials, and offering up to 300Hz full frame rate for tracking fast moving objects. This also is an important factor when catering to certain regional export regulations.

With its newly expanded OEM core product line Xenics is further expanding its reach to the worldwide security systems community. "We are continuously extending our compact and rugged modularity concept, supported by our outstanding mechanical and electronic design group and in-house assembly," says Xenics founder and CEO Bob Grietens. "With the new XCO-640 long-range MWIR surveillance core delivering high stability and superior optical performance we can now offer complete coverage of the infrared wavelength realm."

Like all Xenics OEM modules the new XCO-640 imaging core integrates comprehensive on-board image processing. LACE (local area contrast enhancement) reveals relevant details of a scene unnoticeable due to small temperature differences and long distance capturing. The LACE algorithm, which was substantially improved by Xenics for the XCO-640, dynamically adjusts contrast variations in certain image areas by selectively enhancing bland areas while leaving high-contrast areas unchanged. Xenics' LACE delivers a much better visualization of the objects observed. This will draw attention to incidents that otherwise might be missed.

AGC (automatic gain control) enlarges contrast on a global scale, allowing for manual or automatic control of the sensor's offset and/or gain parameters. NUC (non-uniformity correction) compensates, along with bad-pixel correction, offset and gain variations for a good image under varying environmental conditions.

Since Xenics equips its OEM modules with image processing PCB and selected lens directly built into the rigid core assembly, they offer a real integrated modular solution ready for camera systems vendors.

The rich interface layout of the XCO-640 includes the traditional analog output (PAL, NTSC) or HD-SDI, besides GigE Vision and CameraLink. Digital control is carried out via GigE CP, Serial Channel CameraLink XSP or Serial Control XSP. Pre- and post trigger (in and out) is provided via LVCMOS signalling.
