One comment on “The development of modern metrology and its role today

  1. What is good to know is that even today metrology is based on older techniques for some parts. As the currently sold and used Gauge Blocks, are still made using lapping, as they were invented by Johansson around 1900. Also a reason why they are still called Jo Blocks.
    Of course there have been improvements, and now today there are gauge blocks available, being accuracy down to 50 nm, different materials, etc.
