A Fresnel rhomb is a prism-like device designed in 1817 by Augustin-Jean Fresnel

Today I rode out to the windiest place on the Pacific Coast to see the Point Reyes Lighthouse that came into operation in 1870 and the most amazing "first order" Fresnel lens which didn't fail to impress me.

Hi Ana,
I have been in the lighthouse before. It is truly a jewel of workmanship.
