Product Description

Dia12.7xET2.5mm PMMA Negative Focal Length Fresnel Lenses
 

Fresnel lenses are a type of compact lens originally dsigned by French physicist Augustin-Jean Fresnel for lighthouses, which allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. A Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances.

Applications:

Today, Fresnels are made from glass or plastic and have found many modern uses. Thanks to mechanical glass-milling processes, the lens angles and concentric design can be etched into a single piece of material, rather than individually carved and assembled. One of the most common uses of the Fresnel is in traffic lights, where a strong but not particularly high-quality beam of light is required to alert traffic.

Fresnels are popular in theater and film productions for several purposes. Lenses developed for movies and theater are extremely flexible in design, allowing lighting technicians to easily adjust the light from a clear focused beam to a flooded position that allows a wash of light. The lights are also highly prized for their ability to create hard-edged, clean shadows on stage or in the frame. These shadows allow the light to be better manipulated and controlled, giving lighting technicians the ability to create specific nuances of light.
