Abstract
An apparatus for analyzing light includes an input aperture for receiving light; a first set of one or more lenses configured to relay light from the input aperture; and a prism assembly configured to disperse light from the first set of one or more lenses. The prism assembly includes a plurality of prisms that includes a first prism, a second prism that is distinct from the first prism, and a third prism that is distinct from the first prism and the second prism. The first prism is mechanically coupled with the second prism and the second prism is mechanically coupled with the third prism. The apparatus also includes a second set of one or more lenses configured to focus the dispersed light from the prism assembly; and an array detector configured for converting the light from the second set of one or more lenses to electrical signals.
