Uncertainty of the optical spectral transmittance

Abstract

Determination of the optical filter spectral transmittance takes place at Tartu Observatory and is one of the accredited methods of the Tartu University Testing Centre. Comprehensive characterization of the measurement setup forms the experimental part of this master thesis. The measurement principles, instrumentation, and techniques are described in detail. In conclusion, the uncertainty contributions were quantified, and recommendations were given in order to improve the measurement setup. The thesis can be used as step-bystep instructions when reproducing the characterization of similar systems.
