Portable Spectrometer

Saelig Company, Inc. (Fairport, NY) has introduced the GL SPECTIS 5.0 Touch - a portable instrument for obtaining light measurement data ranging from NIR to UV with laboratory accuracy. Unique features of the GL SPECTIS 5.0 Touch include: laboratory accuracy, extended spectral range from 200 to 1050nm, very high resolution (0.5nm), an OSR system for stray light reduction, and compatibility with a wide range of available integrating spheres and probes for measuring almost any light source from 1 - 200,000lux (Illuminant A).

Photothermal Excitation For Atomic Force Microscopy

Asylum Research (Santa Barbara, CA), an Oxford Instruments company, has announced blueDrive photothermal excitation, an option available exclusively for Asylum’s Cypher™ Atomic Force Microscopes (AFMs). blueDrive makes tapping mode imaging simple, stable, and accurate. blueDrive replaces the conventional piezoacoustic excitation mechanism, instead using a blue laser to directly excite the AFM cantilever photothermally. This results in an ideal cantilever drive response in both air and liquids, which provides significant performance and ease of use benefits for tapping mode imaging.

DOP Meter

Using a patented maximum & minimum search technique, the DOP- 201 from General Photonics (Chino, CA) measures and displays the Degree of Polarization (DOP) of a light source in real time with high accuracy and wide dynamic range. While polarimeter-based systems are expensive and can be inaccurate for low-DOP sources, and polarization scrambler- based instruments are less accurate for high DOP sources, the DOP-201 accurately measures both low and high DOP. It is ideal for characterizing the performances of depolarizers and depolarized light sources, such as ASE and SLED sources and the pumps for Raman amplifiers.

Product of the Month: The RVG200 Videographic Data Recorder

ABB, Warminster, PA, has introduced the RVG200 videographic data recorder with touchscreen technology. The recorder provides easy access to process data for onsite operators, while enabling secure remote access to the same data from any tablet, smartphone, PC, or other networked device. Using iconbased menus or by swiping through the screens, operators can find the process data they need and view it in formats such as individual or grouped charts, bar graphs, or digital indicator displays. The unit is integrated into a plant network through a 100-Mbit/s Ethernet connection. The recorder can notify operators via email of process alarms or critical process events, automatically sent to their PC or smartphone. It can also be configured to routinely email summary reports of process conditions. Up to 24 universal analog inputs enable direct connection of mA, mV, TC, RTD, voltage, and digital signals. Front and rear USB ports permit users to connect a variety of peripheral devices such as a USB memory drive.

Testing Today’s Most Complex Consumer Device: The Ubiquitous Smartphone

We’ve come a long way since Alexander Graham Bell’s famous words, “Mr. Watson, come here” were spoken and the telephone was born. The simplicity of use of today’s smartphones, tablets, and similar smart devices belies the underlying complexity of creating a device that can connect virtually anywhere, at anytime. While there are other consumer electronic devices that have increased in complexity and capability, the majority of the smartphone’s complex structure is completely hidden from the user. At the same time, “when can I upgrade” is a common mantra of users. The fast-paced and high-volume production required in this environment continues to add complexity to mobile device testing, and has necessitated the rethinking of traditional test methods.

Prototype Recovers Lost-At-Sea Images

New hardware built by research engineers at the U.S. Army Research Laboratory (ARL) is helping NASA retrieve experimental images otherwise lost at sea. The hardware weighs less than two pounds, and serves as a means of locating NASA’s flight imagery recorders that capture valuable image data of decelerators during deployment and deceleration. The small box contains a GPS receiver, satellite communications modem, batteries, and a dual-band antenna. NASA’s Jet Propulsion Laboratory (JPL) sought the ARL’s help in ruggedizing a locator unit to limit the risk of losing the data, especially in the event of a catastrophic failure.
