Recording the parallelism of optically contacted Fabry-Perots.
A simple device has been constructed to record accurately the parallelism of optically contacted Fabry-Perots immediately after their manufacture. In this a Fabry-Perot fringe is tuned to be a maximum on-axis by varying the pressure of the gas in which the etalon is emersed. An insect-eye lens is then used to photograph the different fringe patterns from a large number of separate small areas of the Fabry-Perot simultaneously.
