Paper Abstract

The optical paths on the LISA bench must have a length instability of less than 10~pm/square root Hz over time scales of 1s to 1000s. A small rigid interferometer has been constructed to measure the optical path length changes using various bonding techniques. The interferometer was constructed entirely from ultra-low expansion (ULE) glass by optically contacting ULE beamsplitters to a ULE bench. Preliminary results taken with the interferometer operating in air indicate optical path length fluctuations of approximately 100 pm/ sqaure root Hz or less for frequencies between 1 mHz and 1 Hz.
