Advantages of Using Fresnel Lenses
Home » RVs » Fresnel Lenses » Advantages of Using Fresnel LensesFresnel lenses were developed to make life a little easier for the person using them. People who did use them noticed many advantages that they would not have gotten from using conventional lenses. Such advantages made the lens so practical in design and in performance. The lens was made lightweight so it was easier to carry and install. This means that fewer materials were needed to install and maintain the lens. Being modular also accounted for the lenses popularity. If for some reason a crack had formed in the element somewhere, only a small decrease in performance was noticeable. Of course the element was cheap to replace. Today, Fresnel lenses are made from thick sheets of glass or plastic. After the sheets are produced, the lenses are stamped out of the sheets.
Another advantage to using Fresnel lenses is its ability to reduce the amount of energy required to produce light. Instead of using several lamps with reflectors, a single lamp is necessary. This helped to reduce fuel consumption, since the lamp did use oil to burn with.
Fresnel lenses were built for a purpose. They were originally designed for lighthouses and still are used in lighthouses. But they are also placed in magnifying glasses, projection TVs, and wherever bright light is needed, or image quality is not such a requirement as the light source may be.
