The Blanco Telescope is equipped with an active optics system in which variable pressure is applied to the rear surface of the primary mirror via 33 pads. This system can modify the figure of the primary to improve image quality. Normally, the the calibration of this system is verified and, if necessary, modified using ImAn every few months.
The primary mirror is supported radially by 24 lever arms articulated to push on the mirror from below and to pull on it from above. These are not normally adjustable.
