Plasma monitoring with modular, high-resolution spectroscopy

This article is brought to you by: 

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.

Every grain counts

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

Real-time monitoring of LED greenhouse lighting

This article is brought to you by: 

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.

Spectroelectrochemistry Applications and Instruments

This article is brought to you by: 

Spectroelectrochemistry is an extremely valuable tool to study any mechanism that involves an electron transfer. By combining the best of both the electrochemistry and spectroscopy worlds, it allows researchers to probe a range of reactions and extract valuable information that each technique could not achieve on its own.

How multi-line lasers simplify and help commercialise biomedical imaging systems

This article is brought to you by: 

Multi-line lasers are an attractive alternative to laser combiners to simplify fluorescence-based imaging instrumentation. Furthermore, they help commercialise new, cutting-edge imaging systems for clinical use. This white paper explores the advantages of a permanently aligned multi-line laser, giving examples of how such a laser is used in microscopes developed at Julius-Maximilian-University of Würzburg and the University of Washington.
