The Spectrograph of Solar Selection Coatings
Abstract: In this paper, the designing principal, the construction and the optical measurement system of the solar selective coatings spectrograph were introduced. The measurement system consists of sample heating system, vacuum system, optical system, water-cooling system, high-precision integrat- ing-sphere reflecting measurement system, temperature test and control system, computer data acquisition system and so on. The spectrograph can be used for critically measuring the spectral emissivity characteristics with wave of 300 nm - 10,000 nm from indoor temperature to 500˚C and the measurement precision is better than 3%. It provides the necessary foundation for research of new solar selective coatings and manufacture of high-efficiency solar collector.
