Fresnel Lens - Pensacola Lighthouse Royalty-Free Stock Image

View from inside the Fresnel lens of the historic Pensacola lighthouse on the U.S. Naval station at Pensacola, Florida on a sunny day. Sunshine breaks into a starburst of light as it reflects off one of the many facets of the lens. Some of the inner workings of the lens and light mechanism are visible, silhouetted in black against the lens itself. Rainbow patterns of refracted light play on the silhouetted mechanism. Once critical for navigation in the Gulf, the lighthouse is a popular tourist attraction at the naval station on the Gulf coast of Florida.
