Optical Emission Spectroscopy (OES) is a widely used analytical technique used to determine the elemental composition of a broad range of metals. It is an extremely time-efficient and accurate method ...

An optical spectrometer is an instrument used to measure properties of light over a specific portion of the light spectrum, which has found a wide range of practical applications. Dispersive optical ...

Schematic illustration of the electrical spectroscopy on the polaritonic-based graphene photodetector. Image credit: ICFO/ David Alcaraz Iranzo. While the use of polaritons for light confinement is an ...

Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables.

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

Meet the world’s smallest optical spectrometer. Crafted from a single nanowire less than 100 µm long, the device can measure the intensity of colored light across the visible spectrum and may ...

Achieve imaging up to 12 mm in air at 800 nm with the NEW Cobra-D OCT spectrometer, ideal for ophthalmology and industrial applications. OCT imaging has traditionally required the use of longer ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

Researchers present the integration of a detector system and a polaritonic platform in the same 2D material, enabling for the first time the detection of 2D polaritonic nanoresonators with spectral ...
