The technology for making the optics for Hexagon was, I suspect, used elsewhere in Perkin-Elmer for the optics to make the high-resolution “wafer steppers” that printed sub-microscopic lines on the silicon chips that made the PC/internet revolution possible.
For years, P-E was the leading manufacturer of these systems.
In the early ‘90s, they had to spin off their wafer stepper business, which carried on for a few years as SVG, then as SVG-L, and then as ASML.
Interesting. I’m always whining that they don’t make anything in CT anymore.
