WebA flat lens is a lens whose flat shape allows it to provide distortion-free imaging, potentially with arbitrarily-large apertures. The term is also used to refer to other lenses that provide a negative index of refraction. Flat lenses require a refractive index close to −1 over a broad angular range. In recent years, flat lenses based on metasurfaces were also demonstrated. WebIndex 1.5 is often called “low index”; indices up to 1.56 are generally described as “mid index” and those including 1.59 and above are called “high index”. Plastic materials (such as nylon, polycarbonate,…) can be found within the 1.5 – 1.71 range of indices, whereas glass reaches 1.9.
