A normal incidence spectrometer was absolutely calibrated for light 700–1250 Å in the first order and 350–650 Å in the second order using synchrotron radiation at the Photon Factory, National Laboratory for High Energy Physics. The spectrometer was equipped with a 0.4 m, 2400 grooves/mm ruled concave grating with an Al$+$MgF2 coating and a blaze angle of 6.9°, and a multichannel detector. Synchrotron radiation was monochromatized by a 1 m Seya-Namioka monochromator, and the absolute intensity of the incident photon flux was measured with a windowless far-UV photodiode calibrated at the National Institute of Standards and Technology, USA. The error in the sensitivity calibration was estimated to be 13–35%. The spectrometer is used to study impurity behaviors in the JT-60 tokamak.
