Abstract
A primary concern of any device that uses prisms is the fact that prisms are inherently dispersive. Risley prism optical steering devices are made of two or more prisms rotated about a common axis. Dispersion is the fact that any homogeneous glass will refract each wavelength differently because the index of refraction of a material is not constant across wavelength. Risley prisms have other positives that broadband systems would like to make advantage of, and dispersion is their primary roadblock. This paper will investigate two possible solutions to the issue of dispersion in prisms. Examples will be generated for the visible, short-wave infrared, mid-wave infrared, and long-wave infrared broadbands of each dispersion removal method. Lastly, a real world prism using one of these methods was tested.
