Transmission measurements of optical materials involve spectrometers with a range of 200 nm to 900 nm that measure optical components such as filter glass, window materials, etc. Using an integrating sphere (also known as an Ulbricht sphere), these measurements can also be used for the determination of the spectrally resolved backscattering of solid sample surfaces. Another spectrometer is available for the registration of fluorescence and excitation spectra of liquid samples. This type of spectral analytics is indispensable in drug research where information on potential contaminations or changes in samples are of great importance.

Many technical materials, particularly biologically important substances, can be definitely characterised and analysed using IR spectroscopy. We use an FTIR spectrometer, which, when combined with a step-scan unit, ATR unit or fibre-mounted external sample positioning systems, enables the entire range of IR analyses be carried out.
