Acrylic Fresnel Lens: A series of concentric grooves on a flat, thin piece of plastic makes possible a large diameter, lightweight and inexpensive lens with a short focal length. Each groove acts as
a minute refracting facet capable of bending light, thus giving greater transmittance than a conventional lens of the same focal length.
