Mount galvo mirrors on shafts - this should be done with torque wrenches to specs provided from Cambridge Tech
Recommended torques for galvo mirrors and galvos
14 mm x mirror .05” screw socket, 2 inch-pounds torque
...
x mirror 110 inch-pounds torque
Zero the For this entire procedure: zero the X, Y inputs to the galvos – this can be done with a 50 Ohm terminator or short circuit
...
8) Do fine adjustment of voltage offset to hit 8° exactly (voltage in this instance was 1.511 V; 2nd time 1.587 V). GETTING THE Y MIRROR RIGHT IS IMPORTANT
9) Mount the other Y 2 mirror, adjust position so beam perpendicular; position singal is at -4.8mV
10) adjust X angle so that beam emerges level with table,; note position signal is at 0.6 mV
