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

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

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 by ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Master Bond UV15-7LRI produces durable, tough and chemically resistant bonds, seals or coatings with excellent optical and electrical insulation properties. It has a low 1.481 refractive index and a ...

I. Positive (normal) dispersion. This is what happens in most light-matter interaction. The medium has higher index of refraction for higher frequencies; the frequency components of a pulse are ...
