Yup, though the $50K was specifically the R&D cost to develop a technique for making the lens. It used a nano-scale pattern on glass to focus light via diffraction, as opposed to standard refractive lenses or mirrors. The ultimate goal was to develop a process for manufacturing these lenses en masse, for deployment in a large particle detector where traditional lenses wouldn't work. They succeeded, and nowadays (6 years later), they can basically print the pattern using the same techniques as in microchip manufacturing. Back then, though, there was just then one prototype that represented that $50K of research, so I am really glad I didn't fuck it up haha
