“The Point Source Microscope is a great tool for all types of measurements. I’m retired but some years back we had Bob make a cementing station using the PSM. I had a project that had Germanium and Silicon lenses around 8” diameter I needed to center. The clear aperture was out to the edge so using a stylus was not a good choice. I took the PSM off the cementing station and set it up to use to center the lenses on a custom made lathe.
It worked perfectly allowing me to center down to .0001″ using the image provided by the PSM and connected to the computer provided. It’s very versatile for many applications, as I used it also in cementing of lenses. This was all done at Kreischer Optics, with my great friend and owner Cody Kreischer who I dearly miss.”
