The scan mirror mechanism (SMM) enables a slit-spectroscopic observation system to diagnose physical quantities of an astronomical object in the two spatial dimensions. The SCIP (Sunrise Chromospheric Infrared spectroPolarimeter), onboard the international joint balloon project SUNRISE-3, adopts the slit-scan observation system to diagnose the physical quantities in the solar chromosphere precisely. Since magnetic elements in the chromosphere has broad spatial scales and they behave highly dynamic, the SMM needs to scan rapidly and widely with high accuracy. To meet such requirements, we have developed the SMM in which the mirror tilt is controlled by electro-magnetic actuators with sensing tilt by gap-based capacitance sensors. The optical measurements verified the performances required to the SMM; a wide scan range (larger than +/- 1005 arcsec in mechanical angle), high stability (3σ less than 1 arcsec), and rapid response (shorter than 32msec). Thermal cycling tests and thermal vacuum tests have verified that the SMM achieves such performances in the thermal-vacuum environments expected in the balloon flight.
