Stage Construction Options

/VAC3              Vacuum preparation of stage to 10^-3 torr

/VAC6              Vacuum preparation of stage to 10^-6 torr

Contact Factory for Custom Options Available

Optional mirror face aligned to rotation axes — the mirror cell may be offset so the mirror face is at the AZ/EL intersection as a special order system; additional counterbalance weight may be needed for this configuration; please consult factory for details

External cable CMS; larger clear aperture available through AZ; limited AZ travel

Limit switches and hard stops available

Slip ring for customer signals and power
