Paper Abstract

A high finesse piezoelectrically controlled and scanned Fabry-Perot interferometric system has been developed for high resolution studies of spectral lines from extended astronomical objects such as comets and diffuse nebulae. The instrument has a resolving power (at Ha) of ~4x10 4 and is superior to conventional pressure scanned Fabry-Perot spectrometers in its finesse, range of scanning, and ease of operation. This paper describes the basic design and operation of the instrument.
