WAVELENGTH CALIBRATIONS

 

Wavelength calibrations are made by moving a screen over the fibers and illuminating the screen with a bank of Hollow-Cathode tubes. Either Th-Ar or Cu-Ar sources are available. To switch sources, the OT must swap a connection located on the fork of the telescope underneath the instrument.
