When a pre-aligned camera and spectrograph package has been purchased the camera comes pre-tted with a 
ange. This ange accurately locates the camera and ange assembly to the spectrograph body via precision pins and 
matching bushings (see gure below). The camera and ange assembly can be easily be removed and re-attached 
without the need for additional calibration, or readjustments.
