Indian Astronomical Observatory, Hanle
Hanle Faint Object Spectrograph Camera is an optical imager cum spectrograph built collaboratively at the Copenhagen University Observatory.
The instrument is a focal reducer type of instrument allowing for a larger field coverage for a given detector, and also low and medium resolution grism spectroscopy. It is possible to shift between the imaging and spectroscopic modes of operation in seconds.
