Spectral Sensors

The new Spark-VIS spectral sensor from Ocean Optics (Dunedin, FL) measures over the visible wavelength range of 380-700 nm. Available in both OEM and stand-alone configurations, the compact Spark-VIS provides simple absorbance, fluorescence, and emissive color measurements. The device can be embedded to power portable and Internet-connected sensing devices; integrated directly on processing lines; or used as a benchtop instrument.

Accelerometers

Meggitt (Irvine, CA) has introduced the Endevco® 35B triaxial IEPE accelerometer. The adhesively-mounted 35B places three transducers (measuring acceleration in x, y, and z axes) and integrated electronics into a 0.235-inch, 0.55-gram cube. Sensitivities of 2.5 mV/g, 5 mV/g, or 10 mV/g are available.

Pressure Sensors

Measurement Specialties (Hampton, VA), now part of TE Connectivity, has released the MS5837-30BA, a low-power, compact, gel-filled pressure sensor with an I2C bus interface and high resolution of 2 mm. The device has a 3.3 × 3.3 × 2.5-mm ceramic- metal package. The pressure sensor features a delta sigma ADC that offers 24-bit pressure and temperature values, while using 0.6 μA. The sensor has a response time of 0.5 ms, as well as a pressure range of 0 bar to 30 bar in temperatures from -20°C to +85°C. The anti-magnetic, stainless-steel cap and silicone gel protect the internal electronics and provide water resistance. The I2C bus allows the sensor to interface with other microcontrollers.

Gas Sensors

ENMET (Ann Arbor, MI) has announced the GSM-60, a microprocessor-based gas monitor. The system incorporates an internal sample draw pump and gas sensors. The GSM-60 can be custom- configured, with both internal and external sensors for monitoring VOCs, dew point, oxygen, and CO, or a number of other target gases, including O3, HF, HCl, and Cl2. The monitor can also be connected to a range of remote 4-20 mA toxic or combustible gas sensor/transmitters.

Samarium Oxide Glaze

Developed for high-energy pulsed Q-switching infrared laser applications, a new, high-absorption samarium oxide glaze from Morgan Advanced Materials (Windsor, UK) means it is now able to offer three grades of glaze for laser systems. The samarium glaze absorbs radiation at the Nd-YAG lasing wavelength of 1064nm, and its further transitions near 940nm, 1120nm, 1320nm and 1440nm. A significant amount of fluorescent radiation at the lasing wavelength escapes laterally from the laser rod into the surrounding pumping cavity. Absorbing this radiation prevents it from being reflected back into the laser rod, which would in turn stimulate decay from the upper laser transition level, thereby limiting the number of excited ions which can occupy that level.

Deep UV Luminescence Spectrophotometer

McPherson (Chelmsford, MA) has announced a new vacuum ultraviolet universal spectrophotometer, an optical test system optimized for emitting samples like phosphors or photo- and electro-luminescent crystals. It can measure reflectance, transmission and fluorescence emission over its complete working range, 120 nanometers to 2.2 microns. The sample chamber includes high efficiency toroidal optics for focused excitation and sensitive detection. It can operate purged or under vacuum and can interface to commercial cryogenic and heated sample mounts.
