Newtonian Reflector

 

a type of reflecting telescope in which the rays reflected by the primary parabolic mirror are intercepted by a plane mirror and reflected to the side of the telescope tube, where the light-receiving equipment is located. Used only in small telescopes, it was designed by I. Newton around 1670.
