small-footprint spectrometer
Ocean Optics has expanded the capabilities of its small-footprint near-infrared spectrometers with the introduction of NIRQuest512-2.5, a high-resolution device with response from 900-2,500nm. The NIRQuest512-2.5 is well suited to laser characterisation and applications requiring longer integration times. a high-stability, 512-element Hamamatsu indium gallium arsenide (InGaas)-array detector doubles the amount of pixels previously available in the 900- 2,500nm range, significantly increasing optical resolution. Depending on the user-selected configuration of grating options and optical bench entrance slit size,
Elemental analysis system
Photon machines (Redmond, Washington, USa) has added the Spectrolaser system, developed by Laser analysis Technologies (LaT), to its line of LIBS-based (laser breakdown spectroscopy) elemental analysers. The Spectrolaser is designed
for rapid analysis of elemental concentrations using LIBS. The Spectrolaser system software is compatible with both traditional analysis methods and advanced
optical resolution as good as 4.1- 6.3nm (FWHm) is possible. The lower overall dark noise of the system enables longer integration times, which are especially useful in low light level environments. Users are able to capture data
when an external event occurs, or to trigger an event after data acquisition, with the spectrometer’s external hardware triggering functions. Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform. In addition, NIRQuest512-2.5 can be bundled with the company’s Remora network adapter to turn the system into a multi-user spectral data server over Ethernet or existing Wi-Fi connection.

near-infrared photon counter
ID Quantique has released its id210 advanced system for single photon detection at telecom wavelengths, i.e. 1,310nm and 1,550nm. It provides high performance
in high-speed gating at internal or external frequencies up to 100mHz. Photons can be detected with probability up to 25 per cent at 1,550nm, while maintaining the dark count rate at low levels. Timing resolution as low as 250ps can be achieved. The id210 provides adjustable
delays, adjustable gate duration from 1ns to 20ns and adjustable dead time up to 100us. For applications requiring asynchronous detection scheme, the id210 can
chemometric methods, allowing instantaneous reporting of quantitative elemental concentrations from each sample measured. Benefits of the method include speed, simplicity, multi- element analysis capability, and the ability to measure light elements such as C, B, Be, and Li, with which many other methods have difficulty. LaT is a subsidiary of XRF Scientific, and both companies are based in australia.

new series of single photon counting modules
Laser Components has expanded its Count series of single photon counting modules to include the new CountBlue devices. The new devices combine the low count rates of the company’s existing modules with even higher detection efficiencies at shorter wavelengths. more than 60 per cent of incoming photons can be detected at 405nm, more than 65 per cent
operate in free-running mode with detection probability of 2.5 per cent up to 10 per cent. a practical user interface is supplied, with all parameters intuitively adjusted with direct access buttons and the wheel on the id210 front panel. The device provides universal compatibility with external scientific equipments. Inputs and outputs are compatible with most electrical standards: NIm, LVTTL/ LVCmOS, NECL,
PECL3.3V and PECL5V. The detector contains counters
providing detection, clock, gate, aux1, aux2, and the aux1 and aux2 coincidence rates. Inputs aux1 and aux2 are linked to a two-channel event counter and a coincidence counter as an auxiliary block.

can be detected in the green, and detection efficiency in the red is typically greater than 50 per cent. The excellent short wavelength performance makes the CountBlue suitable for fluorescence measurement and microscopy applications. The device features the
same robust design as the existing Count modules, and its optional fibre connector allows easy plug-and-play operation.
