Who has an unobstructed view, leads. But this does not only apply to large lenses - micro optics are gaining in the optical sector. This is often achieved with complex systems, either hybrid or made in one piece. The manufacturing processes are varied and have reached the sub-nanometer range. This is our domain, here is the home of the FRT metrology tools.
