Abstract

29 optogalvanic lines of argon have been observed between 367 nm and 422 nm in a commercial hollow cathode tube. The analysis of the interference pattern arising from a quartz window requires only three reference points to allow direct wavelength calibration with high accuracy. The reported optogalvanic lines of argon yield an abundant number of reference points in the near-uv and extend the range of previously recorded optogalvanic lines of argon and neon in the visible. The version of the technique reported here provides an inexpensive and convenient yet highly accurate means for wavelength calibration in this region of the spectrum and is especially suitable for the calibration of dye or other tunable lasers. © 1993.
