主要特點：
The UV/VUV - spectrophotometer system is a product of more than twenty years of research in the field of production and testing of advanced optical components for UV/VUV spectral range. The current system is based on a prototype spectrophotometer of the Laser Zentrum Hannover e.V., which was initially developed for typical analytical tasks in optical thin film technology. During the production phase of more than ten units for industrial companies and research institutes, the measurement performance of the system could be improved to an outstanding level, which qualifies the spectrophotometer in routine quality management and research applications.
