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.
