Great Lakes Crystal Technologies (GLCT), a high-tech startup in Michigan’s Capitol Region, is pleased to announce that the company has been awarded a Phase II Small Business Technology Transfer (STTR) grant by the US Department of Energy for its proposal entitled “Large Diffraction Grade Single Crystal Diamonds Grown by CVD.” The value of the Phase II grant is $1,093,088.00.

This Phase II grant is a follow-on the GLCT’s Phase I project with the same title which was carried out between June 2020 and February 2021. As was the case for the Phase I project, GLCT’s Chief Scientist Paul Quayle is the Principal Investigator, Michigan State University (MSU) is the Phase II STTR Research Institution, and Fraunhofer USA Center Midwest (Fraunhofer USA CMW) is a subcontracted partner to GLCT.

GLCT’s president and CEO, Dr. Keith Evans, commented, “This project is hyper focused on the development of a minimum viable product in the advanced x-ray optics space. It leverages decades of leading edge research and development at MSU including MSU’s close collaboration with Fraunhofer USA CMW to advance the technology of diamond crystal growth. Additionally, our commercialization plans benefit from a close partnership with Inrad Optics, a US-based global-leader in the supply of advanced crystalline optics.”
