Paper Abstract

The Large Optical Generator (LOG) was originally installed as a precision generator at the University of Arizona. It has since been relocated to the Steward Observatory Mirror Laboratory, where, in addition to its tasks as generator, it can be reconfigured as a polishing machine. As such, utilizing the Mirror Lab's stressed-lap techniques, LOG has recently finished a series of three 3.5 meter mirrors to high accuracy. It is currently configured as a generator for work on the 6.5 meter MMT upgrade. LOG's operating parameters and level of performance both as generator and polisher will be discussed, along with some of the unique safety features that have been built into its operation.
