Abstract
A continuously anamorph-changeable collimated anamorphotic prism system in spectrograph is presented here. It is the unique one which can change its own anamorph-ratio continuously and conveniently among all the non-collimated and collimated anamorphotic optical systems. An important advantage of this system is that we can manufacture in optics more easily, cheaply, precisely and fastly. It is more simple to get different anamorph-ratio than other systems needed to interchange different sets or optical elements. That is another important advantage.
