Testing of the "Tor Vergata" Fabry-Perot interferometer prototype

In this contribution we present preliminary mechanical and optical tests of the Fabry-Ṕerot interferometer pro- totype developed at the "Tor Vergata" University Solar Physics Laboratory. Fabry-Ṕerot narrow filters are of great interest for the study of extended astronomical sources, such as the solar photosphere and chromosphere. The high transparency of the instrument allows for the necessary high time-resolution for fast dynamic processes observations. A dedicated software has been developed to control both coarse and fine piezo-actuated move- ments, allowing for fast (1ms) tuning capabilities. General mechanical behaviour has been tested for use at the focal plane of ground based telescopes and in the perspective of a new space-qualified prototype.
