Abstract: The invention is directed at a miniature grism system. The miniature grism system is a single compact device that comprises a grism with collimating and focusing optics. In an aspect, the grism includes at least one prism and a grating. In an aspect, the miniature grism system, and more specifically the grism, includes at least one prism which is placed on either side of the grating. The focusing optics and the collimating optics are found on opposite sides of the grism system, sandwiching the prism and grating of the grism. In an aspect, the miniature grism system is configured to be retained within a filter wheel. The miniature grism system is configured to be used with telescopes having a small focal ratio.
