September 21, 2024

This page is meant to provide a list of references that are directly relevant (marked with a *) or in some cases marginally relevant to the topic of resolution loss in roof prisms and the so-called phase coatings used to mitigate the problem. If you know of any additional literature, please email me at hurbenm … More Technical References for Roof Prism Resolution Loss, Phase Coatings, and Related Topics

The Physics of Roof Prisms and Phase Coatings, Simplified: Part III

August 18, 2023

Diffraction patterns and resolution In the previous post we traced the passage of light through an Amici roof prism, which required decomposing vectors into components, accounting for phase shifts upon reflection, and then looking at how the waves will be recombined. We can now see that there will be an opportunity for interference effects to … More The Physics of Roof Prisms and Phase Coatings, Simplified: Part III

The Physics of Roof Prisms and Phase Coatings

July 22, 2023

I’ve written a technical article on the topic of why the roof prisms used in binoculars require specialized coatings in order to improve their performance. I was prompted to pull this together because I couldn’t find a single reference that traced through this interesting problem in a non-trivial way. The article includes a derivation of … More The Physics of Roof Prisms and Phase Coatings
