Model 205 Spectrometer

Outstanding features of the Model 205 include a dual grating turret which accepts Snap-In gratings for easy interchangeability and an optional f/4.4 aperture ratio. Use as a spectrograph with a 30 mm flat field focal plane or as a scanning monochromator to expand instrument versatility. Two entrance and exit port locations simplify set up of experiments.
