Researchers Test Galaxy-Seeking Robots

A telescope project from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) will use a planned array of 5,000 galaxy-seeking robots to produce a 3D map of the universe. Dubbed ProtoDESI, the scaled-down, 10-robot system will help scientists achieve the pinpoint accuracy needed to home in on millions of galaxies, quasars, and stars with the Dark Energy Spectroscopic Instrument (DESI).

Additive Manufacturing Design Considerations For Production In Aerospace

Written by: Caitlin Oswald As additive manufacturing continues to mature from a fad to a robust production process, complementary methods of designing for additive manufacturing need to develop. Today the majority of design engineers were trained under conventional education methods of subtractive manufacturing. Switching that paradigm will take more than adjusting a few rules, but an evolution in education. When designers are urged to be creative the design space box expands exponentially when using additive. This new idea of starting from nothing instead of starting from a block of material becomes limitless for young design engineers. However, the fast pace of additive manufacturing adoption requires those who previously trained for conventional to rapidly rethink the way they design to meet the vast new options afforded by additive. The following paper is Part A of a two-part series focused on Additive Manufacturing Design. The series will condense some of these limitless possibilities, and capture the advancing strategies of additive manufacturing design.

Unlocking the Secrets of Amorphous Metals

What do bulk metallic glasses (BMGs), amorphous metals and liquid metals all have in common? Basically they’re all the same thing – non-crystalline metal alloys that are simultaneously glasses, metals, and liquids. Sounds impossible, doesn’t it? But it’s not. And they possess some incredible properties. Think of them as the shape-shifting superheroes of the materials world.

SLED-Based Broadband Near-Infrared Source

Avo Photonics (Horsham, PA) design, development, and manufacturing, was commissioned by Luxmux Technology Corporation, to develop and manufacture a solid-state, broadband, continuous emitter for use with their line of miniature integrated spectrometers. The emitter combines the outputs of multiple super-luminescent LEDs (SLEDs) into a polarization-maintaining single-mode fiber. Such an accomplishment required collimating multiple beams and achieving collinearity to an overlap of 700 um and pointing to within 250 urad. The result is a >100 mw, fiber-coupled source with continuous emission over the 1250 – 1750 nm band. To learn more, click here.

Short Pulse Seed Laser Diode Driver

Analog Modules, Inc. (Longwood, FL) recently released its short pulse seed laser diode driver, Model 766. The Model 766 offers user-adjustable pulse width capability as low as 150ps up to 1ns for driving 14-pin butterfly packaged laser diode modules at output currents up to 1.1A. Applications include seeding fiber lasers for materials processing, time-resolved spectroscopy, LIDAR and others. The driver circuitry operates from a single 5V power source. All other needed voltages are generated on the board by high efficiency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 3A and voltage capability of 4.2V.

Core Alignment Fusion Splicer

Furukawa Electric (Tokyo, Japan) and OFS (Norcross, GA) recently introduced the FITEL S179 Hand-Held, Core Alignment Fusion Splicer. The FITEL S179 Fusion Splicer can be used on all Metro, LAN and FTTx fibers, including ultra-bend insensitive fibers. The FITEL S179 Fusion Splicer’s large-capacity battery system allows 200 splicing cycles (splicing/heating) in one charge. A 4.3-inch wide LCD screen with touch panel offers easy and intuitive operation and a proportionately wide splicing chamber makes optical fiber easier to load. For improved visibility in low-light conditions, 3 +1 LED lights illuminate the entire splicing chamber. To learn more, click here
