Abstract
An imaging spectrometer to form a spectrally resolved image of an object, the spectrometer comprising three curved reflecting surfaces, an optical path between the object and the image comprising reflections from the three curved reflecting surfaces. The spectrometer further comprises dispersing elements each with a curved surface in the optical path. One dispersing element is located in the optical path between the object and a first of the curved reflecting surfaces; another dispersing element is located in the optical path between the image and a third of the curved reflecting surfaces. The majority of the spectrometer's dispersive power may be provided by optical elements in the optical paths between the object and the first of the curved reflecting surfaces and between the image and the third of the curved reflecting surfaces.
