Dual Etalon Fabry-Perot Optical Spectrometer
GENERAL Apr 2002 The TUG H-Alpha Spectrometer has been designed to produce a partial survey of H-Alpha emission from the interstellar medium (ISM) and selected regions of the northern sky. The instrument is designed to be used in coude focal system of 1.5 m telescope (RTT150) located at Bakirlitepe, Antalya. A dual-etalon 7.5 cm Fabry-Perot spectrometer in its primary spectral mode, will sample sky with 4 minutes of arc resolution. Spectral resolution of the spectrometer is around 20 km.
The instrument is produced with the collaboration of Cukurova University Physics Dept., ADANA, METU Physics Dept./ Astrophysics Group, ANKARA, Sabanci University/ Astrophysics and Space Program, ISTANBUL and Turkish National Observatory ( TUG) of Turkish Scientific and Research Council ( TUBITAK).

HARDWARE Nov 2002
Optics:...Basic optical system is composed of dual pressure chambers with 7.5 cm Fabry-Perot Etalons. Above the chambers there is a H-Alpha filter to limit bandwidth to desired values. Below there is a camera lens and CCD imager.Mechanics:...
Mechanical layout of the spectrometer includes two pressure chambers, filter and camera lens housings above a stable frame. CCD camera dewar goes under the chambers. There are vacuum and pressure tight windows between the sides of the chambers on the optical path.
