Fresnel Lens Replicas

These Fresnel lens replicas are made of optical acrylic prisms, brass frames and cast iron and brass pedestals. They are authentic full scale replicas.  The prisms are machined and polished according to Fresnel's original formulas.

4th order fixed and 6th order rotating replicas with pedestals on display at the Ponce Inlet Lighthouse, Florida

4th order fixed lens replica manufactured for the Old Plantation Flats Lighthouse replica in Virgina Beach.

Tinted Acrylic Prisms

The greenish hue that is apparent in historic Fresnel prisms can be replicated.  The photo on the left, shows acrylic prisms with no color adjacent to historic prisms.  In the photo on the right, acrylic prisms on the bottom row have been tinted to match the historic prisms directly above.  The Coast Guard used these replica prisms along with historic prisms to resore a 4th order fixed lens.  See photo below.
