The National Astronomical Research Institute of Thailand has developed since June 2014 an optical laboratory that comprises all the activities and facilities related to the research and development of new instruments in the following areas: telescope design, high dynamic & resolution imaging systems and spectrographs. The current activities comprise: i) the development of a focal reducer for the 2.4 m Thai National Telescope, ii) the development of the Evanescent Wave Coronagraph dedicated to the high contrast observations of star close environments and iii) the development of spectrographs for the TNT and for the 0.7 m telescopes of NARIT regional observatories.
In this presentation, I first will give an overview of the NARIT optical laboratory team and facilities. Then, I will describe the following projects: the TNT focal reducer, the high resolution spectrographs and the Evanescent Wave Coronagraph. Finally, I will describe our future plans.
