Fiber Optic Connectors

Single Step Polishing After Laser Cleaving With the standardization of 4G wireless, the increase in cloud storage and computing, and the push for faster network data rates, the highest quality passive interconnect systems must be used. While the robustness and size of these interconnections, fiber types, and cable management all play major roles in the backbone, what happens at the tip of the connector also greatly affects the optical performance of the system.

Intelligent Photonic Multi-Sensor Solutions

With the Internet of Things (IoT) quickly rising in front of us, it would be easy to get caught in the trap of thinking that both the trajectory and applications will be somewhat predictable. While hindsight is 20/20, the future can be a little trickier to envision. We can likely all agree that when we saw the first brick-sized wireless telephone, it wasn’t hard to tap our creative problem solving to conclude that subsequent generations were going to get smaller, cheaper and generally “better”. But few people could have envisioned the “smartphone,” let alone Apple’s first edition iPhone. Fewer still looked from that first brick to an age of sensor-driven, cloud-connected apps in the palms of our hands.

UV-VIS Micro-Spectrometer

Hamamatsu Corporation (Bridgewater, NJ) has announced the release of the C12666MA microspectrometer, a UV-VIS spectrometer about the size of a fingertip. Its miniature components, fabricated using MEMS (micro-electro-mechanical systems) technology, allow it to be a fraction of the size of traditional spectrometers. In addition, its hermetically sealed package makes it usable in high-humidity environments that traditional spectrometers do not tolerate well.

UV-Visible-NIR Polarization Spectroscopy

CRAIC Technologies (San Dimas, CA) recently announced the addition of UV-visible-NIR polarization spectroscopy capabilities to CRAIC microspectrophotometers. This feature is offered as a package that allows the user to measure polarization spectra in either transmission or reflectance modes. With the ability to measure polarization microspectra™ in the ultraviolet, visible and near infrared regions, the UV-visible- NIR polarization package represents a powerful new tool for both materials science and biological research.

Shock-Sensing Apparatus

This apparatus enables easy and reliable shock detection and localization in high-speed inlets of aerospace vehicles. John H. Glenn Research Center, Cleveland, Ohio Acompact shock-sensing device, which employs an innovative light sheet generator, has been created. The device may be used either as a solo aerodynamic shock detector or in combination with a scanning mode shock sensor. This permits easy detection and tracking of unstable and traveling shocks in supersonic inlets.

High-Performance Photocatalytic Oxidation Reactor System

Airborne volatile organic chemicals are oxidized using blue LEDs, fiber optics, and visible light-activated catalysts for space and terrestrial air purification. Marshall Space Flight Center, Alabama As crewed space missions extend beyond low Earth orbit, the need to reliably recover potable water is critical. Aboard the International Space Station (ISS), the water is recycled from cabin humidity condensate, urine distillate, and hygiene wash wastes. In spacecraft cabin air environments, off-gassing from equipment, human metabolism, and human personal care products contributes to significant airborne concentrations of volatile organic compounds (VOCs). These polar and water-soluble compounds ultimately dissolve into the humidity condensate and stress the process load, logistics costs, and lifecycle requirements of the water processing systems. The aim of this effort was to develop the High Performance Photocatalytic Oxidation Reactor System (HPPORS) technology for the destruction of airborne VOCs prior to reaching the water processing systems. This innovation will reduce the logistics costs and lifecycle requirements of water processing systems, and help extend NASA missions to include long-duration space habitation and lunar and Mars colonization missions.
