A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

There is always something interesting to find when browsing the projects on Hackaday.io. I’m always amazed at how much hackers can get done in their basements and home labs. One surprising trend I’ve ...

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 ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

The significance of the entrance slit and the diffraction grating in forming a spectral image of the incident light in the image plane is discussed in the articles “An Introduction to a Spectrometer: ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS In a study published in Light: Science & Applications, researchers from Diamond Light Source (United Kingdom), ...

Hamamatsu Photonics has introduced a UV model of its ‘micro’ spectrometer series. C16767MA is sensitive across 190 to 440nm with a typical resolution of 5.5nm (FWHM, so ±2.25nm to 50%). Update: scroll ...
