Two-Axis Gear-Drive Gimbal

AMG-GR gear-driven motorized gimbals from Aerotech (Pittsburgh, PA) provide economical, high-accuracy elevation- over-azimuth positioning. The AMG-GR standard circular cells range from 100 mm to 300 mm in diameter. Cell mounting options include a centered (balanced) cell or a front-surface reflection option where the front of the optic is located on the axes of rotation. Special configurations can accommodate non-circular optics, cameras, sensors, and round optics larger than 300 mm in diameter. The modular design permits each gimbal mirror cell to be easily modified or replaced with different shaped cells to accommodate sensors or other asymmetrically-shaped payloads.

SWIR Camera

The XEVA-2.35-320 TE4 from Xenics (Leuven, Belgium), a thermoelectrically cooled infrared camera features T2SL infrared detection technology and delivers superb performance in the 1.0 to 2.35 μm wavelength region for hyperspectral imaging or laser beam analysis. The new XEVA-2.35- 320 TE4 digital camera delivers 14-bit images at high frame rates of 100 Hz, 350 Hz or higher in windowing mode. It consists of a 320 × 256 T2SL detector array with pixel pitch of 30 μm at a pixel operability ratio of > 99%. The detector head is cooled with a four-stage thermoelectrical cooling element, operating down to 220K, and is integrated into one single compact housing with all control and communication electronics.

Fiber Optic Cleaning Tools

MicroCare Corporation (New Britain, CT) has introduced the newest additions to its STICKLERS® family of fiber optic cleaning tools. Sticklers® CleanClicker™ push-to-clean tools contain more than 750 cleaning “clicks” and can clean both male jumpers and female ports. CleanClicker™ tools are available in three sizes: for the 2.5mm configurations, the 1.2mm configurations, and the fast-growing MTP/MPO design often used in data centers, central offices and cable TV head ends. Pressure applied to the end-face is reduced, which minimizes the chance of scratching the end-face or damaging the connector.

Generating Broadband Terahertz Radiation from Microplasma in Air

Researchers at the University of Rochester’s Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. Fabrizio Buccheri and Xi-Cheng Zhang recently demonstrated that an approach for generating terahertz waves using intense laser pulses in air – first pioneered in 1993 – can be done with much lower power lasers, a major challenge until now.

Enhancing Neutron Imaging with Grazing Incidence Optics

Marshall Space Flight Center, Alabama A low-cost optical element was developed specifically for neutron optics applications. The technology operates as a reflective lens — similar to proven grazing incidence optics used for x-ray imaging — and improves neutron imaging resolution for applications using low-energy (<1 electron volt) neutrons.
