The Fresnel magnifying glass is an ultra-thin magnifier made of transparent acrylic (though other materials can also be used).
Fresnel magnifying lenses made of PMMA can have a minimum thickness ranging from 1 mm to 2 mm, unlike traditional magnifying lenses (convex lenses),
Its surface is covered with minute striations, within which numerous convex lenses—referred to as ring-like structures—are embedded. These structures cause the light passing through them to bend, thereby giving rise to diffraction.
This results in an image that is magnified by the same factor. Fresnel lenses are characterized by higher brightness and a flat surface compared with conventional lenses, as well as a larger illuminated area.
Conventional convex and concave lenses typically have very limited diameters, whereas Fresnel lenses have proven highly effective in the field of magnification, achieving performance that conventional lenses simply cannot match.
Moreover, the Fresnel magnifying lenses produced today are only 1–2 mm thick, making them highly portable; their primary purpose is to reduce the weight and bulk of conventional magnifiers made from acrylic or glass.
Our company’s high-definition reading magnifier is manufactured using the principle of Fresnel lenses and is widely used in educational demonstrations, as well as for elderly individuals reading books, newspapers, and maps, and for cultivating edible mushrooms.
Custom-made upon customer request.
Features: High magnification, scratch-resistant, shatterproof, lightweight, highly transparent, and easy to use.

A Fresnel magnifying glass is an ultra-thin magnifier made from transparent acrylic (though other materials can also be used). Fresnel magnifiers made from PMMA can have a minimum thickness of just 1 to 2 millimeters, setting them apart from traditional magnifiers (convex lenses).
