Circle no. 54 New Spectroradiometer System Designed For LED Measurement
Photon Control, Inc is pleased to announce the release of a new Spectroradiometer System to Photon Control’s Spectroscopy product line. Photon Control’s Spectroradiometer System was specifically designed for LED testing and analysis, boasting high performance and accuracy, in a robust and portable design.
This Spectroradiometer System is not only used for spectrophotometric measurements of emission sources of LEDs, but in addition can also be used for lamps and other illuminants. When the radiometric calibration is applied to the SpecSoft software it calculates and displays the radiometric spectrum and radiant flux. SpecSoft provides an interface for acquiring a reflectance reference and a dark reference.
Photon Control’s Spectroradiometer is a complete measurement system that includes software, USB cable, user manual and an external power adapter. With five different models available, covering wavelengths of 220-1050nm, this Spectroradiometer System is well suited for a number of applications in OEM and laboratory environments such as: agriculture lab testing, quality control lab testing and food processing to name a few.
Circle no. 55 Fast-Response Mass Spectrometer
The 3F-series of quadruple mass spectrometers from Hiden Analytical now feature direct digital signal detection for our fastest response and most sensitive detection levels, addressing the needs of the researcher operating in the UHV/XHV vacuum regime through to specialised fast-event gaseous studies at pressures to atmosphere and beyond. The system integrates triple-stage mass filter technology with digital data acquisition by direct positive ion counting (pulse counting) to combine a continuous detection range of seven full decades with a detection rate from just 1 ion per second and abundance sensitivity measurements to the parts per billion regime. The integral data accumulation mode enables operation with time-functioned data acquisition for suppression of fundamental ion statistical noise. Vacuum partial pressures to 5x10E-15 mbar are detectable. Ionisation source options are available for conventional residual gas analysis, for surface desorption studies and for molecular/laser beam measurements. Single-stage and multiple-stage pressure reduction systems are available for operation at higher pressures beyond the UHV range. Requirements for measurement of externally generated positive ions and for measurement of both positive and negative ions are addressed by the alternative EP/EQ series. A custom design service is available for specialised applications.

Spectrometers Head to Mars
Three Ocean Optics instruments have begun their eight-month journey to Mars. Customised HR2000 spectrometers are a part of the ChemCam unit on NASA’s Mars Science Lab rover, Curiosity, launched November 26, 2011 from Cape Canaveral, Florida. Ocean Optics supplied three modular HR2000 high-resolution miniature fibre optic spectrometers that were configured for analysis of Martian rock and soil composition using Laser Induced Breakdown Spectroscopy (LIBS). A laser mounted to the mast unit of the ChemCam instrument can fire at targets up to nine meters away, generating a series of laser pulses, the light from which is collected for the LIBS analysis. The modular design of the HR2000, with selectable optical bench options such as detector, grating and entrance aperture (slit), made it an ideal choice for the mission. Each ChemCam spectrometer is configured to detect elemental signatures over a different wavelength of light: 240-336nm, 380-470nm, and 470-850nm. The use of the three spectrometers simplifies the design and creates redundancy, as many elements under study have spectral lines in more than one of the spectral ranges covered by the three units.

Another reason the HR2000 was chosen for this mission was its reliability – a must for remote space operation where maintenance is impossible. Because the spectrometer contains no moving parts to fail, it can withstand the G forces associated with space travel. Additionally, the spectrometers were modified to handle extreme temperature ranges, radiation, shock and vibration. The Curiosity Rover has been described by NASA as having the most advanced scientific instrumentation ever used to study the surface of Mars. With the analysis enabled by Ocean Optics’ equipment, sample analysis is exponentially faster. On prior missions, the time required to determine composition of a single sample was two to three days; ChemCam’s output is anticipated to be one dozen compositional measurements per day. This is not the first space voyage for Ocean Optics equipment. In 2009, the company also collaborated on the ALICE spectrometer, which was instrumental in detecting the presence of water ice on the moon. Other NASA researchers have utilised Ocean Optics spectrometers for applications both on Earth and in space.
