Fresnel Lens in Rogers City at 40 Mile Point
Augustin-Jean Fresnel was the inventor of the most commonly used beacon in lighthouses. So we offer this 4th order Fresnel lens which is used in the 40 Mile Point Light a few miles north of Rogers City as a way of saying Happy Bastille Day! Fresnel was born in 1788 in France. Unable to speak until he was 8 years old, he was really a mathematical and scientific genius who died when he was just 39 years old. His blending of lenses and prisms made him the father of modern lighthouses. The 40 Mile Point Light was constructed in 1897 and is still in use today. You can climb it all the way to the top.
