Made In Champaign County


Inprentus manufactures the most efficient high line density diffraction gratings in the world. Inprentus was founded in June 2012 by University of Illinois Urbana-Champaign physics professor Peter Abbamonte to commercialize an innovative nano-scale scribing technology, which is a technique for carrying out precision lithography via mechanical deformation of metallic surfaces.

The company, based in Champaign, 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 research scientists use diffraction gratings in spectrometer and monochromator instrumentation. They use infrared, ultra-violet and x-ray radiation to study the properties of novel materials, pharmaceuticals, environmental science, physics and life sciences, which advance the core research of a long list of large industries.
