External light sources as well as internal ones (UV LED and Xenon high pressure) can be used for analysis. The high pressure xenon lamp can tune the intensity to the sample absorption; thereby strongly absorbing samples may be measured. Instead of a cell (cuvette) a transparent tube can be inserted into the light path. The same sample can be measured in the transmission- as well as the dispersion (900 angle) measurement. The spegg®, calibrated by a norm light source, can determine radiation intensities of external light sources e.g. of the sun in mW/nm *m² . No additional power supply is requirded, control and power supply are carried out through the USB interface. The intuitive spegg® graphic software supports obtaining and processing of spectral signals; e.g.absorption, transmission, enzyme kinetics, device functions making use of scilab® and LabVIEW ™ software.
