Abstract

An imaging telescope including a first mirror configured to receive electromagnetic radiation having a first polarization state and to reflect electromagnetic radiation having a second polarization state, the first mirror including a multi-layer dielectric (MLD) coating configured to convert the first polarization state to the second polarization state, and a plurality of reflecting configured to receive the electromagnetic radiation having the second polarization state reflected from the first mirror and to reflect and focus the electromagnetic radiation having the second polarization state onto an image plane of the imaging telescope.
