Mirrors are rarely used dynamically during beam operation and as such they can be treated as static systems. Therefore, above the determined value from each facilities floor spectrum, the vibration amplitude becomes negligible. Extensive factory testing has shown, above a threshold value, there is no correlation between the actual vibrational stability of systems and their first natural frequencies. Furthermore, water cooled systems typically do not lead to increased 1st natural frequency, even though marginal increases in vibration are experienced. It is also shown utilization of coupled optical geometry provides the lowest vibrational performance. Therefore, does the trend of increasing the specification of the 1st natural frequency provide a cost effective and functional approach to real-world optical system design? Or should a holistic approach involving beamline design, optical layout and manual alignment techniques be used to realize ultimate vibrational performance?
