Testing for Covid-19 has been a critical part of every country’s response to the pandemic. Back on the 16 March, the World Health Organisation’s head, Tedros Adhanom Ghebreyesus was telling countries ‘test, test, test’; South Korea, in particular, has been praised for its approach to controlling the spread of the virus through extensive testing early on when its outbreak first occurred.   Read More

In mini-spectrometers, gratings – the wavelength dispersive element – generate wavelengths at higher orders than the primary wavelengths to be detected. These higher order wavelengths are fractions of the primary wavelength, and, if the spectrometer covers less than one octave, are spatially separated by angle. If the ratio of upper to lower wavelength is larger than two, the orders begin to overlap and must be removed or sorted out before they reach the detector.   Read More
