Vertical cross table: Travel across the incoming beam
±15mm (motorized)

Travel along the incoming beam
±15mm (manual)

Lifting table: Travel ±5mm (motorized)

UHV vacuum chamber with built–in mirror bank: UHV vacuum chamber with stationary baking facility.
Mirror bank with cardanic mirror suspension.

Motorized mirror adjustment with angular encoder for pitch movement
(Rp=±1mrad; dRp=0.005mrad)

Motorized mirror adjustment with angular encoder for roll movement
(Rr=±7mrad; dRr=0.1mrad)

Motorized mirror adjustment with angular encoder for yaw movement
(Ry=±5mrad; dRy=0.25mrad)

The mirror is indirectly water-cooled.

Optical surface of the mirror: 20x100 mm

A lifting unit lowers the mirror bank, if necessary.
Thus the beam passes the mirror chamber without being influenced
