The Hydra bench spectrograph uses a "Bench Schmidt" camera of 400mm focal length which uses a SiTe 2K x 4K detector with 15u pixels. Please click here if you need information about this camera and CCD.
Before 2000, Hydra was used with an "Air Schmidt" camera, with 229mm focal length and a Loral 1Kx3K detector with 15u pixels. Please click here if you need information about this combination. Note, however, that this camera has been retired and is no longer available for use.
