Hamamatsu Photonics
Hamamatsu Photonics is a Japanese maker of light-sensing and light-emitting products: photodetectors, cameras, light sources, lasers and measuring systems built on its own compound-semiconductor technology. In 2024 it bought NKT Photonics, a Danish maker of fiber lasers.

Its parts sit inside chipmaking and inspection tools, including the laser engines in DISCO's stealth dicing machines, and its NKT Photonics unit builds lasers for trapped-ion quantum computers; but it sells to many industries (medical, scientific, industrial), and AI is not its main economic driver.
Sells optical sensors, cameras, light sources, lasers and systems to equipment makers, research labs and manufacturers, and licenses its stealth dicing patents to system makers.
Japan (Hamamatsu)
Semiconductor manufacturing equipment. The highly specialized machines and design software used to create advanced chips in the first place. Without these tools, no chip maker in the world — including the ones building NVIDIA's chips — could produce anything.
