ATT185 Tilt Table

Description

Design Features

  • Sub-arc-second resolution
  • Decoupled, orthogonal tilting movement
  • High thermal stability

The ATT185 series precision tilt (pitch-roll) tables provide a means for leveling instruments or tilting components over a ±10° range. Aerotech’s patented* sub-arc second resolution drive allows the user to cover the total angular range quickly while maintaining a resolution of 0.2 arc second for the ATT185-3, and 0.1 arc second for the ATT185-5. With this unique drive, the tables exhibit virtually no creep or backlash and have excellent repeatability. These tables have a gimbal support with decoupled and orthogonal axial motion.

Both tilt table bases have clearance holes for M6 screws on 25 mm centers and are adaptable to Aerotech linear or rotary translation stages. The tables are constructed of aluminum with a black anodize finish.
