Inprentus Makes Final Four in ‘Coolest Thing Made in Illinois’ Contest

EnterpriseWorks graduate company Inprentus Inc. made it to the final four of Makers Madness, a bracket-style tournament that celebrates the work and diversity of the manufacturing sector in Illinois presented by the Illinois Manufacturers’ Association.

Although Rivian’s all-electric R1T truck was awarded the title of the ‘Coolest Thing Made in Illinois’, Inprentus was also feted by Illinois Governor J.B. Pritzker during a ceremony at the Governor’s Mansion in Springfield.

The contest highlights innovative products from across the state. 450 products were entered into the contest this year, and over 200,000 votes were cast by the public to nominate the ‘Coolest Thing Made in Illinois’. 

Inprentus makes custom blazed diffraction gratings. These highly precise gratings are utilized in x-ray and ultraviolet experiments at various scientific research institutions. They are also used in optical components for semiconductor manufacturing, augmented and virtual reality glasses, and in materials, chemistry, and life sciences research.

Inprentus competed against General Mills’ Fruit by the Foot, the Rivian Automotive electric truck, and Ingersoll Machine Tools’ components for the Orion spacecraft capsule in the final four of the bracket-style tournament.

Following its graduation from EnterpriseWorks, Inprentus opened a corporate headquarters in Champaign. It designs and manufactures diffraction gratings sold to Fortune 500 companies, academic institutions, and government laboratories around the world.

Inprentus was started in 2012 by University of Illinois physics professor Peter Abbamonte. The company was created with the mission to advance the manufacturing of precision optics using proprietary nano-scale contact-mode lithography techniques.
