Here’s Looking At You, Fresnel Lens

Today’s post is all about the fresnel lens.

The Fresnel Lens was developed by French physicist Augustin Fresnel.

You can read more about the fresnel lens in the book A Short Brght Flash by Theresa Levitt: A Short Bright Flash

This was my view of the first-order fresnel lens at Absecon lighthouse in Atlantic City, New Jersey on September 20, 2014.
