We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but here we are with [Twisted & Tinned], who’s made a novel clock with a ...
Diffraction gratings are periodic optical structures that disperse incident light into constituent wavelengths by interference. They form a cornerstone of modern optical instrumentation, underpinning ...
First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...
IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This echelon diffraction grating came ...
Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...
Robert Ball’s drawing of a prominence from visual observation. From Robert Ball, “Story of the Sun”. London, Cassell, 1893. Since many historical solar instruments have similar sounding names, a ...
UV-visible spectroscopy is an analytical technique used to study the absorption or reflectance of ultraviolet and visible light by a sample. Being relatively inexpensive and easily implemented, this ...
Abstract: The design and development of portable plasmonic embedded measurement systems represents a significant engineering challenge, aimed at delivering the high sensitivities observed in devices ...

Design and fabrication of a dual laser Raman spectrometer with a single one-dimensional CCD detector
The combination of two spectrometers in dual-laser Raman devices without the need for moving parts represents a significant advancement. This study focuses on design and fabrication of a dual ...
Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.
