Abstract
We recently had two occasions to qualify optical flats of moderate size. Because of the mounting geometry, it was convenient to try measuring them with a Fizeau test against a liquid surface. In a preliminary literature search, we found few writings on the application of liquid flats. In this report, we briefly review the literature before describing our experiences and results.
