Indigenous spectrograph developed

A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate. The Aries-devasthal Faint Object Spectrograph & Camera (ADFOSC) has been developed by Aryabhatta Research Institute of observational sciences (ARIES), Nainital
