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.
Matthew Dale speaks with the developers of the world’s first dual-comb spectrometer with an acquisition speed of 10 gigahertz
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
Due to climate change, population growth and many other factors, farms will need to adapt to ever-worsening conditions. Spectroscopy plays a key role in developing the future of these farms.
A modular spectroscopy setup based on an Ocean Insight HR series high resolution spectrometer was used to monitor changes in argon plasma emission following the introduction of different gases to a plasma chamber. The measurements demonstrated the viability of modular spectroscopy components to acquire plasma emission spectra in real time from a plasma chamber. Plasma characteristics determined from these emission spectra can be used for monitoring and controlling plasmabased processes.
How will the world feed 10 billion people by 2050 with no new land for agriculture? Greg Blackman speaks to machine builder Bühler about how optical sensing can maximise yield in grain processing
New methods and instruments are building on impressive investigative capabilities, finds Andy Extance
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.
Controlling the quality and yield of crops will be crucial elements of increased food production. Growing crops in greenhouses and vertical farms (greenhouse factories) will allow us to better control the process of growing food and, in the case of vertical farms, move food production closer to the consumer (vertical farms can be integrated into existing structures such as warehouses). In greenhouses, LEDs are a popular lighting option to provide the spectral energy to crops for photosynthesis and other growth processes.
This whitepaper will explore how optical sensing is used for real-time monitoring of LED greenhouse lighting, and how this can be used to manage colour and power output.
This whitepaper details the use of differential optical absorption spectroscopy (DOAS) for monitoring complex emission spectra easily and cost-effectively
