Inprentus, Inc.

Inprentus manufactures the most efficient high line density diffraction gratings in the world. The company, based in Champaign Illinois, manufactures blazed diffraction gratings used at a growing list of synchrotrons and free electron laser facilities around the world. These are large government-operated research facilities where scientists use diffraction gratings in spectrometer and monochromator instrumentation. These facilities utilize infrared, ultra-violet and x-ray radiation to study the properties of materials, chemical compounds, and pharmaceuticals, with applications in environmental science, physics and the life sciences.  These important studies advance the core research of a long list of significan industrial, research and educational institutions.

About Diffraction Gratings

Grating Cropped - taken by Cody.jpg

A diffraction grating is a periodic structure patterned into a reflective surface, which disperses light into its constituent wavelengths.

  • Gratings separate light into its "colors", similar to a prism.

  • Allows one to control and manipulate light.

  • Used in all applications in which the wavelength of light must be tuned (spectroscopy, imaging, etc.), including beamline monochromators, FEL self-seeding, and x-ray emission spectrometers /RIXS.

About Our Technology
