One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

It’s a relatively simple task to find evidence of helium by just looking at the sun; all you need is a prism, diffraction grating, and a web cam. DIY spectrometers have been around for ages, but most ...

Researchers developed a process to turn crab shells into a bioplastic that can be used to make optical components known as diffraction gratings (in the tweezers).

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Calculated diffraction pattern on a two-dimensional Raman induced grating as a function of the diffraction angle and pump field intensity. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...

Structured Illumination Microscopy (SIM) is a tool which breaks the diffraction resolution barrier to provide resolutions of up to 20nm. The resolution of conventional microscopes is limited by the ...
