A novel spectral test station can assess diffraction grating efficiency at specific wavelengths by simultaneously indexing incident wavelength and the unit being tested.ERIK SCHOEFFEL, MCPHERSONDiffraction gratings are in most optical spectrometers covering visible, IR and UV spectra. Absorption and emission spectrometers, fluorimeters, inductively coupled plasma instruments and high-performance liquid chromatography equipment all use grating spectrometers. Large monochromators in fusion research, high harmonic generation for attosecond physics and synchrotron radiation all measure very short wavelengths of light in the UV and even extreme UV and soft x-ray wavelengths. Diffraction gratings in extraterrestrial instruments and astronomical telescopes allow light from objects in space...Read full articleRelated content from Photonics MediaARTICLESETH Team Leads Way to More Precise Diffraction GratingsFor decades, scientists have tried to improve the design and production of diffraction gratings, one of the oldest and most important technologies for controlling light.
