Fresnel Rhomb and Other Devices for Handling and Teaching Polarization: Inexpensive Design

摘要

We demonstrate a pair of 90-45-45 prisms from binoculars appropriately attached to serve as Fresnel rhomb, i.e. achromatic quarter-wave plate. One and two Dove prisms with metallic reflection instead of TIR can work as half-wave plate and polarization rotator. respectively; both achromatic.
