On the Passage of Linearly Polarized Light through an Uncoated Roof Prism

September 20, 2024

The famous Zeiss “paper” by Weruach and Dörband (translation attached below) on the development of phase coatings for roof prisms describes a simple test to determine if an optical instrument has coated prisms or not. They describe the use of two linear polarizers with the device placed in between; with phase coating present, one will … More On the Passage of Linearly Polarized Light through an Uncoated Roof Prism
