BACHES Echelle-Spectrograph
$8,000.00
The BACHES Echelle-Spectrograph, shown here with the recommended, optinally available Remote Calibration Unit RCU (on the left, with an SBIG ST 1603 ME camera attached), is a professional spectrograph for precise, high-resolution analysis of spectra. BACHES is an acronym for Basic Echelle Spektrograph.
