A variety of spectroscopic techniques is used in gas analysis and sensing – increasingly important fields, crucial in atmosphere monitoring, emission control and industrial processes efficiency.
Spectroradiometry can help producers and users ensure UV-based virus-fighting equipment really works, finds Andy Extance
To perform measurements on light-emitting objects, it’s important to interpret intensity information provided by the spectrometer correctly. Understanding differences in parameters is key. Read about intensity calibrations in this whitepaper
In this overview, we explore the optical sensing tools and techniques available from Ocean Insight for virus detection. Our focus? Rapid testing and screening for viruses including COVID-19.
Researchers from VTT Technical Research Centre of Finland have developed optical interruption of a midinfrared (MIR) quantum cascade laser (QCL) using a near-infrared (NIR) laser diode for cavity ring-down spectroscopy (CRDS).
Dutch start-up MantiSpectra has received investment from PhotonDelta and Innovation Industries, while Senorics is set to receive more than €2 million from the Development Bank of Saxony
High progress in optoelectronics technology, especially designed for infrared wavelength region (IR), is observed. The use of various spectroscopic methods allows to obtain detailed information on the chemical analysis of the leaking gas. Each of the spectroscopy methods is dedicated to different types of concentration measurements. We encourage you to read the article that explains and presents laser gas leak detection with infrared.
In this application note, Edinburgh Instruments utilises a Transient Absorption Spectrometer featuring dual detector options for direct kinetic and spectral measurements to Study a Molecular Triad’s Photoinduced Electron Transfer Reactions.
This paper explains how to use the MID-IR linear detector array in the sorting area. High performance optical sorting systems are the main application of multielement detectors. Optical sorting can be used in the mining, food, chemical and pharmacological industries.
The laser operates in fundamental mode with beam quality M2 < 1.05 for both beams. The beam shape is recorded at the output of the oscillator (magnified image of the output coupler) on a WinCamD-LCM-NE 1” beam profiler at the nominal operation point of the laser with 3.7 A pump current, approx. 7.8 W total pump power and 440 mW average output power from each comb.
The new development paves the way for portable dual-comb light sources for applications such as spectroscopy and precision distance measurement
