| Zusammenfassung | A double ended interferometer (DEI) is an alternative design for traceable measurement of the absolute length of gauge block shaped bodies without the need of a platen to be wrung to one of the faces. In spite of this general advantage, until now it doesn't exist a well established DEI-system at any National Metrology Institute (NMI). PTB, as the NMI of Germany, plans to develop a dedicated DEI which is situated in a temperature stabilized vacuum chamber. A Prototype of DEI was built at PTB in order to study the measurement principle and potential challenges to be taken into consideration for the final design. This paper describes the experimental set-up and measurement procedures of the prototype. First results indicate that the current design is a good basis for the final version of DEI at PTB. |
