Inprentus

Inprentus is an American precision optics company based in Champaign, Illinois, founded in 2012 by University of Illinois Urbana-Champaign physics professor Peter Abbamonte. The company commercialized a dual-atomic-layer nano-scale contact-mode lithography and mechanical ruling process for manufacturing blazed diffraction gratings — ultra-precise diffractive optical components that control and disperse light with high efficiency. Rather than selling only catalog parts, Inprentus positions itself as a custom solutions partner, working from first principles with customers' engineering teams to define, manufacture, and verify gratings tailored to specific optical systems. The company's blazed diffraction gratings serve several demanding industries. In augmented reality (AR) and mixed reality, Inprentus produces waveguide grating masters — input, expansion, and output gratings that can be patterned on a single substrate — enabling high-efficiency light coupling for AR glasses and headsets. In semiconductors, its gratings support metrology, inspection, and advanced lithography-related optical systems. It also supplies synchrotron and free-electron laser (FEL) beamlines, spectroscopy systems, space-based imaging, and defense optics. The company describes its technology as enabling high line-density gratings with line densities from 50 to 6,000 lines per millimeter and facet angles from greater than 0.1 to 85 degrees, with no restriction on grating size and support for 4-inch, 6-inch, and 8-inch wafers or photomasks. Inprentus markets itself as offering end-to-end solutions spanning design, manufacturing, and metrology, with more than a decade of experience in grating design, manufacturing, and metrology. Its customers include synchrotron facilities, semiconductor manufacturers, augmented reality developers, government laboratories, and advanced research institutions around the world. The company remains privately held and is headquartered in Champaign, Illinois.

Inprentus was founded in Champaign, Illinois, in 2012 by Peter Abbamonte, a physics professor at the University of Illinois Urbana-Champaign. The company was established to commercialize a new approach to nano-scale lithography and mechanical ruling — a dual-atomic-layer contact-mode lithography process — that had originated in university research. This technology was adapted to the manufacture of blazed diffraction gratings, optical components that disperse light into spectra with high efficiency and are critical in scientific instrumentation and advanced optical systems. From its origins as a university spin-out, Inprentus grew into a precision optics company serving synchrotron facilities, semiconductor manufacturers, augmented reality developers, government laboratories, and advanced research institutions around the world. Its proprietary process combines nano-scale contact-mode lithography with mechanical ruling to produce high line-density gratings with the accuracy required for applications such as AR waveguides, semiconductor tools, synchrotron and FEL beamlines, spectroscopy systems, and other advanced optical applications. Over its first decade and beyond, Inprentus expanded its product and industry focus. It developed blazed diffraction grating masters for AR waveguides, supporting input, expansion, and output gratings for augmented reality and mixed reality displays; precision-blazed gratings for semiconductor metrology, inspection, and lithography-related optics; gratings for synchrotron and free-electron laser beamlines; spectroscopy grating masters; and optics for space-based imaging and defense applications. The company emphasizes an end-to-end approach spanning design, manufacturing, and metrology, and states that it has more than ten years of experience in grating design, manufacturing, and metrology. It remains headquartered in Champaign, Illinois, and privately held.
