DARPA looks to Sensors Unlimited for dual-wavelength focal-plane array
Sensors Unlimited Inc. in Princeton, N.J., won a contract from the U.S. Defense Advanced Research Projects Agency (DARPA) Microsystems Technology Office (MTO) in Arlington, Va., to develop a 1280-by-1024-pixel, dual-wavelength, visible and shortwave-infrared focal-plane array (FPA). The uncooled, InGaAs array will enable high-resolution, passive night-vision imaging with sensitivity to wavelengths from 0.4 to 1.7 microns using pixels on a 15-micron pitch. The contract will be awarded in three, 12-month phases and if fully executed, will total nearly $4.6 million. The development of this FPA will result in breakthrough advances in focal-plane-array performance. The new FPA will have less than 10 electrons readout noise while operating at video rates.

StockerYale offers double-clad ytterbium fiber for fiber-laser applications
StockerYale Inc. in Salem, N.H., is introducing ytterbium (Yb)-doped fiber for fiber lasers, which are gradually replacing conventional Nd:YAG lasers in applications such as laser marking, material processing, welding, surgery, and free-space communications. “Due to recent technological advances, fiber lasers are expected to capture an increasing percentage of the industrial laser market,” says Mark W. Blodgett, chairman and chief executive officer of StockerYale. “Unlike solution doping, StockerYale’s proprietary rare-earth doping process provides for high quantum efficiency and high rare-earth concentration because of more-uniform homogenization of rare earth into the glass matrix, adds Rick Tumminelli, StockerYale’s manager of specialty-fiber operations.

Newport unveils ultraviolet refractive beam shaper
Newport Corp. in Irvine, Calif., introduced the GBS-UV-H refractive beam shaper. Optically designed without an internal focus for higher-energy pulsed and CW lasers, the device is optimized for ultraviolet (UV) laser input at 248 to 365 nanometers. The shaper delivers efficient beam shaping necessary for applications such as material processing, micromachining, annealing, lithography, nonlinear optics, optical data storage, and cell sorting. The device’s “refractive design enables customers to convert a Gaussian laser beam into a collimated flattop beam with nearly 100 percent efficiency,” says Steve Peterson, product manager for optomechanics and subassemblies at Newport. The shaper produces a collimated flattop beam by point-to-point mapping of the Gaussian input rays to redistribute the intensity to a flat-top output. The collimated output beam can be easily manipulated and resized with conventional imaging optics. The device uses low dispersion refractive optics with high-efficiency dielectric antireflective coatings. For more information contact Newport online at www.newport.come/UVbeamshaper.

The DRS Infrared Technologies unit in Dallas will provide Standard Advanced Dewar Assemblies Type I (SADA I) units, which are infrared detector and cryogenic cooler assemblies. Deliveries are to be completed by June 2007. The Apache Arrowhead generates a high-resolution image from the pilotage FLIR sensor that displays in the cockpit and on the pilot’s helmet-mounted display. The U.S. Army is expected to purchase more than 700 Arrowhead systems to outfit its AH-64 Apache fleet by 2009.
Edmund Optics offers clear-optical-path USAF targets
Edmund Optics in Barrington, New Jersey is releasing the new Clear Optical Path USAF targets, manufactured from an extremely thin electroformed nickel substrate. Because there is no glass in the pattern area, light travels only through air, eliminating chromatic and absorption issues. The target pattern covers from group 0, element 1, to group 3, element 6. A user card is included to illustrate where each group and element is located. The target can be used for very deep ultraviolet, x-ray and far-infrared applications.

KVH receives $3.2 million order for fiber-optic-gyro-based systems
KVH Industries Inc. in Middletown, R.I., received a $3.2 million order for its fiber-optic-gyro (FOG)-based TG-6000 precision inertial measurement unit (IMU). The order came from Raytheon Integrated Defense Systems. The TG-6000 IMU will serve as a key component in the guidance system of the U.S. Navy’s next-generation MK 54 lightweight torpedoes. Delivery of the TG-6000 IMUs ordered during this initial contract will begin later in 2005 and continue through 2007. If three follow-on options are exercised, the total order is potentially worth more than $15.8 million between 2005 and 2009. The KVH TG-6000 measures rate and acceleration precisely in three dimensions, critical for the navigation of a torpedo or other smart munitions. The IMU uses a three-axis configuration of KVH’s FOGs, which have an all-fiber design and digital signal processing for reliability and accuracy. The MK 54 lightweight torpedo is the next-generation antisubmarine-warfare (ASW) weapon. For more information contact KVH online at www.fiberopticgyro.com.
OIP Sensor Systems delivers military night-vision systems
OIP Sensor Systems in Oudenaarde, Belgium, won two separate contracts to deliver military night-vision systems in Europe and in South America. OIP won a contract from an unspecified South American country for 100 driver night vision viewers for armored personnel carriers. Drivers of closed-hatch vehicles benefit from clear daylight viewing conditions at night with OIP’s night-vision viewer. The display viewer with integrated imaging intensifier tube provides the driver with passive driving capability at night. Separately, OIP won a contract to build 500 LORIS night-vision monocular sights from an undisclosed European customer. The sights are being delivered with Photonis-DEP’s high quality XD-4 as well as its XR-5 image intensifier tubes. Deliveries are scheduled for the end of this year.
