SOFTWARE SPECTROSCOPY THz time-domain spectroscopy systems
Menlo Systems has introduced a new generation of THz time-domain spectroscopy (TDS) systems with improved features. THz-TDS systems with an optomechanical scanning unit, like the Tera K15, Tera Sync, and TeraSmart, provide >5THz spectral bandwidth and >90dB signal-to-noise ratio. With the latest fibre coupled photoconductive
Software for analysing quantum correlations
PicoQuant has released the QuCoa software package, an integrated solution for data acquisition and analysis using the T2 time-tagging mode of PicoQuant’s TCSPC electronics. QuCoa is aimed at research areas relying on coincidence detection such as Hanbury-Brown-Twiss set-ups to study single photon sources (g(2) / antibunching), quantum key distributions (QKD), general quantum optics, or the study of entanglement using Hong-Ou Mandel set-ups (HOM). The software offers special analysis routines for coincidence correlations as well as for coincidence counting applications. The QuCoa software features one
of the fastest software correlators for coincidence correlation, which permits the correlation of the absolute arrival times of photons in real time. This allows, for example, the assessment of the quality of an anti-bunching curve already during the measurement. The g(2)(0) value and count rates on all
detectors are continuously calculated and displayed.
THz antenna technology, new software and system hardware, and modular design, the new generation of THz systems offers high flexibility and versatility with respect to system configuration and arrangement for a wide range of uses in THz spectroscopy and imaging. The novel ‘ScanControl’ software is intuitive and easy to use, including new features and enabling centralised control of all system components, such as the lasers and amplifier drivers, or synchronisation electronics.
Handheld spectrometers
Gamma Scientific has announced its new line of high- precision handheld spectrometers. The unit is particularly well adapted for applications in horticulture, photography, visual merchandising, health and safety and general research. The unit has also generated interest among
manufacturers and installers of lighting solutions, whether traditional lamp-based sources or LED devices. The PG100N model provides a robust and reliable solution for
Menlo Systems’ igure 9 technology for
fibre laser mode-locking guarantees robust systems with highly reliable and reproducible performance. Options like multichannel outputs, and add-ons such as the imaging unit Tera Image, an additional scanning unit for THz spectroscopy of optically excited samples, or advanced THz evaluation software, hold solutions for the most demanding tasks.

light measurement with fully NIST-traceable performance. Through an integrated, high resolution colour display, parameters such as LUX, CCT, chromaticity, CRI and SPD can be viewed instantaneously. Its CMOS linear image sensor is effective
from 380nm in the UVA to 780nm in the near-infrared. In addition to internal data logging, downloads via an SD card, USB port or wi-fi mode allow data tracking and analysis with download capability in Excel and JPG formats. The detector head can be removed for optimal positioning and the operating time is up to five hours on a full battery charge.

ANALYSIS, TEST AND MEASUREMENT
Laser beam monitor for additive manufacturing
MKS Instruments has released the Ophir BeamWatch AM, a non-contact laser beam monitoring system for additive manufacturing. BeamWatch AM is a lightweight, compact system designed for real-time measurement of focal shift during laser start-up of powder bed fusion manufacturing processes. It measures key
beam size, position, and quality parameters, including focus spot size and beam caustic. These measurements allow users to more easily determine when the beam is aligned and in focus, providing more consistent metallurgy. Measurements can be displayed as tabular, 2D, and 3D views, providing a quick and realistic display of laser characteristics. BeamWatch AM is the next

generation of MKS Instrument’s laser beam monitoring systems, which all use Rayleigh scatter to image the beam without contact. This removes potential for damage to the laser and speeds the measurement process by up to two minutes. The system can measure laser powers to 1,000W in-situ, at rates up to 14Hz.
