The UV-VIS-NIR spectroscope "Lambda 900" is being used the determination of transmission and reflection in a maximum range of 175 - 3300 nm. In combination with theoretical modelling, a wide range of material parameters can be calculated from this data e.g. to control the quality of thin films. Typically, the films are deposited on substrates with dimensions ranging from about 20 x 20 mm² up to 100 x 100 mm². Liquid samples are measured in cuvettes.
We offer transmission and/or reflection measurements as a service for companies and institutions in or beyond the field of photovoltaics.
