It’s not just Kodak but the entire history of Bausch & Lomb, Xerox and other companies that grew out of this place, along with the simple fact that UR’s optics is world class and receives a huge amount of research money. It isn’t just “optics” - as we think of lenses - but they’re doing top work in quantum computing, which involves optics and quantum entanglement (quantum photonics) plus a bunch of other things. That and a host of other related fields. If I remember correctly, it was UR that recently announced the ability to entangle a much larger number of particles. Look at [this one page](Quantum Optics : Research : The Institute of Optics : University of Rochester) about optics and you see that it isn’t about “imaging” in the traditional sense.
