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 is one of the earliest concave ...

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

I GREATLY regret that in a note of mine on a “new mode of using the concave diffraction grating,” in the “Astronomical Column” of March 22 (p. 501), I wrongly interpreted a sentence of Prof Rizzo's ...

The basic function of any spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it via a computer. In ...

Spectrographs are important tools for studying many biological and chemical processes and substances, from pigments to plant growth and nucleic acids to pharmaceuticals, providing information about ...
