By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

MANY microscopists must have had occasion to use the highly refractive gum-styrax as a medium for mounting. The genus Styrax is, I believe, native in Western Asia and Asia Minor, but which of the ...

Researchers in Korea have created a new metamaterial with the most extreme positive index of refraction yet – a whopping 38.6. The metamaterial operates at terahertz frequencies and the team believes ...

Blue Fin Vision® is working to redefine cataract care by changing the narrative beyond sight restoration and instead as a life-enhancing ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

Minimizing residual sphere and cylinder is one method of ensuring patient satisfaction after refractive cataract surgery, ...

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 ...
