Paper Abstract

For the past several years, we have been building mechanically tuned birefringent filters for the spectral range 4500 - 7500 Å with bandpasses as narrow as 50 mÅ and stability of better than 5 mÅ. The filters can operate over a spectral range of -5 to 60°C and one version has been successfully shaken to the shuttle bay vibration specification. The tuning techniques used are mechanically simple and require minimal demands on encoders and drive electronics. Tuning to a random wavelength can be accomplished in less than one second while adjacent wavelengths can be reached in a fraction of a second. Tuning also results in considerable relaxation of the environmental requirements of birefringent filters.
