Reminder
• Piet’s proposal: two dowels inserted into two mirror holes (vertical alignment); mirror weight as counterbalance
• Two leaf springs (horizontal alignment); pretensioning in nominal “zero” position
• Piezo actuators out of particles acceptance

Carassiti drawings
• Delivered on june 3• Original (Piet’s) approach: center of horizontal
rotation “on” the mirror• “inverted” approach: center of horizontal
rotation “far” from the mirror• Both taken in consideration
