2 M TELESCOPE - HANLE FAINT OBJECT SPECTROGRAPH CAMERA
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.
