Advances in laser technology have paved the way for the development of powerful, ultrafast lasers with pulse lengths as short as 10fs or less. Building such systems has come with many challenges for the precision optics community. Ultrafast systems therefore require low group delay dispersion (GDD) components to access and maintain femtosecond pulse durations.

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.

Aspheric lenses are an extremely powerful tool for improving the per­formance of optical systems whilst also reducing the number of el­ements and consequently size and weight.

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.

Silicon photodetectors are commonly used for light power measurements in a wide range of applications such as bar-code readers, medical imaging, spectroscopy, and laser printers.  There is another function, however, which utilises the photodetectors as optical position sensors.
