Optical testing

The PIT has a monochromator dedicated to high spectral resolution optical tests: instrument calibration, detector and source characterisation. This equipment, which can be used independently, could also be coupled with the thermal-optical vacuum vessel in order to provide a means of calibration which can be used in a thermal environment.
