Astronomical Spectroscopy with Spectracon Image TubesFootnote

Pages 73-76 | Received 20 Feb 1976, Published online: 22 Jul 2016
 

Abstract

A variety of spectroscopic observations have now been made at Royal Greenwich Observatory using a Spectracon, which is a single-stage magnetically focused image tube with a thin mica output window. When used with highly corrected optical systems and a fine-grained nuclear emulsion, the image tube provides an efficient, high resolution linear detector giving a low noise record.

The principles and practice of operation are briefly described, and results are presented which demonstrate how some of the advantages of electronography can be exploited in stellar spectroscopy.
