Damping is a critical factor affecting the dynamics of resonant scanning micromirrors and the design of their actuator
systems. For any new micromirror design, modeling the damping to sufficient accuracy to predict the performance can
save much effort in testing and redesign. To address this challenge, a simple formula for the air drag on scanning
micromirrors is postulated that contains a drag coefficient, which is treated as a function of the Reynolds number that is
fit to experimental measurements of the damping of two different MEMS scanning mirrors. A formula is found that
describes the drag coefficients for both scanning mirrors for a range of their Reynolds numbers.
