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.

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

An introduction to the theory of polarised Raman spectroscopy and exploring the wealth of sample information that can be obtained using this technique.

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.

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.
