This Spacecraft Optical Test Fixture has a single axis of rotation and a load rating of 600 lbs. Similar to the Dual Axis Rotate and Precision Alignment Fixture, this Aerospace Tool is designed to support assembly, integration and test operations in addition to optical alignment. Clearance lockout features, including lock rods, index locking screws, removable leveling feet (not shown), ensure that, when a 10 gram load is applied, the resulting angular deflection is less than 5 arc-seconds. Shock absorbing casters offer payload protection during transportation. Removable forklift tubes are constructed from aluminum material. Push bars provide an ergonomic interface for the technician to transport and navigate the Aerospace Tool (with payload integrated) through hallways and over varying terrains.
