AGM's core products, including the Electrostatic Variable Optical Attenuator (ESVOA) chip and the 2D MEMS Mirror chip, are built upon basic Optical MEMS technology (micromirror with comb drive actuation). Each mirror is equipped with a pair of polysilicon actuation electrodes located beneath the mirror. 3 words related to accelerometer: measuring device, measuring instrument, measuring system. The second mirror rotates around two axes and adjusts the reflected beam toward the output fiber collimator.
