large fresnel lens

Medium to big Fresnel lenses have a vast range of potential applications. Drivers of left-hand-drive vehicles often use them to overcome the blind spots when they switch to a right-hand-drive system and vice versa. Simple hand-held magnifiers are also commonly made of Fresnel lenses. Fresnel lens glasses are used to correct several visual disorders, such as ocular-motility disorders. You can also use a large size Fresnel lens to provide magnification for a television or computer screen. Some designs are for concentrating sunlight for heating in solar forges, in solar cookers and in solar collectors used to heat water in off-grid housing.

Since plastic solar Fresnel lenses can be made larger than glass, they're usually a better choice for solar applications. Additional applications include photography, lighthouses and performance art. Our selection includes imaging and non-imaginglarge Fresnel lenses. Imaging types incorporate segments with curved cross-sections. They produce sharp images that are in contrast to the flat cross-section of non-imaging lenses that do not produce sharp images. There are two types of imaging big Fresnel lenses: spherical and cylindrical. There are also two different types of non-imaging lenses: spot and linear.
