  Design and operational performance of table-top measurement apparatus is
presented towards direct Planck constant traceable high accuracy and high
precision small forces and optical power measurements within SI unit system. An
electromagnetic force compensation weighing balances, highly reflective mirrors
and high-energy pulsed laser unit (static average power 20 W) are tailored
together with a specially developed opto-electro-mechanical measurement
infrastructure for cross-mapping the scale-systems of precision small force
measurements obtained with a state-of-the-art classical kinematic system
employing Kibble balance principle in the range of 10 nN to 4000 nN in
comparison with forces generated due to quantum-mechanical effect namely the
transfer of the momentum of the photons from a macroscopic object. Detailed
overview of the adapted measurement methodology, the static and the limits of
dynamic measurement, the metrological traceability routes of the measurement
parameters, quantities and their measurement uncertainties, parametric
up(down)-scaling perspectives of the measurements are presented with respect to
the state-of-the-art measurement principles and standard procedures within the
newly redefined International System of Units (SI).
