Discover how wave refraction works, why it happens and how it affects surfing in this easy-to-understand guide.

High index lenses have a refractive index of 1.53–1.74. Polycarbonate, which has a refractive index of 1.59, offers a mix of strength and thinness.

Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest ...

Post-refractive ectasia occurs very rarely, in only about one out of every 10,000 cases of refractive surgery, or 0.09% of LASIK procedures, 0.02% of PRK procedures and 0.01% of SMILE procedures ...

The optical materials presented so far have high transmittance with low refractive index, or, conversely, high refractive index and low transmittance, thereby limiting the production of ...

Among the various sensing modalities available for bioprocess operations, index of refraction (IoR) is intriguing for its simplicity and capability for sample-less, real-time readout. A group led ...

This will potentially allow to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that physicists had about the connection between a ...

The researchers alternately laminated film of this high-refractive-index material and film of a low-refractive-index material to form a dielectric mirror1) and then used the mirror for magneto ...
