Auxiliary Optics

Often, astronomers use additional optics between the telescope and their detector. We can loosely define a camera to consist of any additional optics between the telescope and the detector. This is the most general definition; sometimes, camera is just used to refer to optics which contribute to an imaging system, as opposed to a spectrograph. Here we consider some of the more common optics used in imaging cameras.
