    Abstract: A compact spectrometer that is relatively free of spatial and spectral image distortions. The spectrometer includes one or more slit elements located at an object plane, a first optical sub-system having at least one refractive optical element, one or more dispersive elements located substantially at a center plane, a second optical sub-system having at least one refractive optical element, and one or more one detecting elements located at substantially an image plane. The first optical sub-system is capable of substantially collimating, at the center plane, electromagnetic radiation originating from the one or more slit elements. The second optical sub-system is, in one embodiment, substantially symmetric to said first optical sub-system, the center plane being the plane of symmetry. The second optical sub-system is capable of imaging the substantially collimated electromagnetic radiation from the center plane onto the image plane. Another embodiment has a reflective dispersive element, and the first optical sub-system is also the second optical sub-system, acting as a dual optical sub-system.

    Abstract: The present disclosure provides an optical imager and a method for imaging electromagnetic radiation. In one aspect, the optical imager includes an object array substantially located at an object plane, a first catadioptric element configured to substantially collimate, at a central plane, electromagnetic radiation emanating from the object array, a second catadioptric element configured to image the substantially collimated electromagnetic radiation from the central plane onto an image plane, and a detecting element substantially located at the image plane. The first catadioptric element includes at least one refractive surface and at least one reflective surface, and the second catadioptric element includes at least one refractive surface and at least one reflective surface.
