Increasing data volume and speed enlarge the possibilities of larger CMOS sensors with more and more pixels.
Requirements for precision measurement in machine manufacturing regarding achievable resolution increased over years and are still increasing.
To realize a laser process observation through an F-Theta lens, usually a coaxial imaging path with a telephoto lens is used. Thereby the field of view moves across the scan area along the laser beam.

During the last few years the performance of our computers has increased while their size has been reduced. But there is a physical limit on this development because quantum effects play a significant role on very small sized transistors.
The thermal focus shift is typically a problem caused by optical glass lenses.
