3.5 X Fresnel Lens Full Page Reading Magnifier - 10" x 12"
A Fresnel lens is a type of optical lens that is composed of a series of concentric grooves or ridges on a flat surface, rather than a traditional curved lens. This design allows for a thinner and lighter lens with similar or greater focusing power compared to a curved lens of the same size.
The ridges on a Fresnel lens bend and focus light, similar to the way a curved lens works. However, the ridges are angled to allow the lens to be thinner and flatter. This design makes Fresnel lenses more versatile and easier to use.
Fresnel lenses are known for their light weight, compact size, and versatility, which makes them a popular choice in the magnification field.
Overall, Fresnel lenses are an important tool in optics and can provide advantages in terms of cost, weight, and size compared to traditional curved lenses.This 8"x10" acrylic Fresnel lens is the clearest magnifier of this size.
