Optical Spectroscopy of Glasses

HVG also deals with the evaluation of transmission spectra for the quantitative determination of the colouring ion species. Demands on the analytics induced a continuous development and improvement of the measurement technology and evaluation of transmission spectra within the framework of various research projects. Several HVG spectrometers are available for such measurements.

Three steps describe the procedure for the determination of the components with colouring effect in glasses: measurement of the transmission, calculation of the optical density, determination of the concentration in colouring ion species.
