In TIRF microscopy, fluorescent molecules are in a sample in an aqueous environment that is near a solid with a high refractive index, usually a glass coverslip. At what is called the critical angle, ...

Bound states in the continuum (BICs) are a special class of resonant states. Although they have the same momentum and energy as the propagating modes in free space, yet they are not coupled to the ...

(a) Total internal reflection of two Bloch waves at the interface of the photonic crystal. (b) Guidance condition: as a Bloch wave reflects twice, it duplicates itself. (c) Conventional and ...

Total internal reflection microscopy is a light microscopy technique that relies on total internal reflection of illumination light to generate an evanescent wave that extends less than 200 nm from ...

An LED comprising V-shaped ridges instead of flat wafers offers 20-fold light extraction improvement claim a team of scientists from Japan and France. The researchers say that they have produced the ...

The DeltaVision OMX V4 enables Total Internal Reflection Fluorescence Microscopy (TIRF). This technique uses an evanescent wave to selectively excite fluorophores that are close to the coverslip. This ...
