MWIR Folded Zoom Lens

MKS Instruments, Inc. (Andover, MA) recently announced the Ophir ®LightIR 16-180mm MWIR f/3.6 continuous zoom lens, the newest addition to the LightIR family of lightweight, long-range, motorized continuous zoom lenses. The LightIR 16-180mm f/3.6 is a compact, thermal imaging lens optimized for smaller size 10μm pitch VGA FPA (focal plane array) detectors. It features a folded optics design that makes the lens 65% smaller than existing MWIR (medium wave infrared) 10μm VGA lenses. This makes it suitable for use in small gimbal thermal imaging applications, including drones and tactical UAV IR cameras as well as micro-/mini-tactical payloads in the commercial, homeland security, and defense markets.

Battery-Operated Torque Wrench

RAD Torque Systems (Abbotsford, BC) has launched what it claims is its most advanced battery tool, the BRAD BL S. Like its predecessor, the B-RAD BL SELECT, the new S tool has a brushless motor for speed and efficiency, but it’s integrated with a torque transducer. The B-RAD BL S automatically records all torque cycles, including torque measurements, through the integrated transducer. The data from the torque measurements recorded on each job can easily be retrieved wirelessly with a Bluetooth connection and the RAD software. The B-RAD BL S has torque capabilities of up to 5,000 lb-ft. All RAD Torque tools are calibrated to ISO 17025 standard.

DC-DC Converters

Murata (Smyrna, GA) recently introduced several new non-isolated DC/DC converter lines for distributed power architecture applications. The UltraBK™, MonoBK™, and PicoBK™ series were developed to provide small size, high efficiency, decreased noise, low EMI, and take up less board space. The newest is the UltraBK™ line, comprised of the MYTNA and MYTNC series. Both use patented technology to provide an ultra-thin, high-efficiency package. The expanded MonoBK™ series now includes the MYMGK-H line. Featuring high-heat resistance, it drastically cuts down on both board space and design time. Finally, the PicoBK low-power offering integrates an inductor with a control IC for applications where space is at a premium, such as with wearable devices.

Spectrum Processing Platform

Mercury Systems, Inc. (Andover, MA) recently launched the ground-breaking Rappid™ spectrum processing platform, a modular open system architecture designed to dramatically accelerate the development of a wide range of electronic warfare (EW), signal intelligence and software-defined radio applications. Current EW systems are typically designed and developed with custom hardware, firmware, and software. As new technology becomes available, each new design requires new software development from scratch. In contrast, Rappid empowers system developers to run the same software and firmware on different hardware implementations, enabling quick upgrades across a broad range of EW systems in order to deliver operationally relevant capabilities when and where they are needed.
