Jessica Rowbury looks at the challenges of bringing spectroscopy to the consumer market, and whether we’re likely to see them being used by the
public in the near future
McPherson has released a new vacuum ultraviolet spectral test system, VUV-STS. The system measures reflectance as a function of angle of incidence. It measures optical performance 'at wavelength' and can help determine optical constants. It uses special techniques for measuring non-polarised light and works in the 30 to 160nm wavelength region. Transmission can be measured too, although it is not appropriate for many materials at these wavelengths. Options exist to extend operation up to 300nm.
