Microfinishing Yesterday-Today and Tomorrow from Micron to Nano and Ångström
Space as an Example for Proportions in Size
In space the sun and the moon are well perceptible by their size. The stars are just luminous dots. But the infinite space still hides a indefinable amount of stars and systems.
We are just at the threshold of the infinite space. Technique and research respectively continue requesting precision up to the Ångström (see chart, picture 11).
The proportions in size of the techniques already reached and still to be reached are represented impressively in picture 10.
We will face up to the requirements . Only the lapping and polishing technique can go on this journey ….. we are highly motivated. Good luck on your journey, travel with us.
