The UV-VIS-NIR spectrometer is able to monitor transmission and specula reflection spectra within the ultra violet to the near infra-red range. This technique testifies the transmission of optical coatings on glasses or the reflection of reflective surfaces. Furthermore it determines the characteristics of carbon nano tubes. In addition it is possible to determine the photocatalytical activity by measuring the reduction of methylene blue according to DIN 52980.
