Abstract : Imaging of the solar photosphere started in the beginning of the 17th century and continued for next three centuries. In early 20th century the spectrograph and scanning systems were built to study the solar chromosphere. By the mid 20th century, several telescopes with reasonably large size could make the observations of the solar photosphere and chromosphere at high-resolution. Furthermore, to probe the Sun at ultra-high resolution (50-70 km spatial scale), building of larger aperture telescopes continued well into the 21st century. Newly built/planned telescopes are equipped with state-of-the art back-end instruments capable of making solar photospheric and chromospheric observations simultaneously at high spectral and temporal resolutions. In my talk, I will review the status of new generation large solar telescopes with emphasis on a variety of back-end instruments planned/built to achieve various science goals.
