|Title:||New Ultraviolet Radiometry Beamline at the Synchrotron Ultraviolet Radiation Facility at NIST|
|Published:||January 01, 1998|
|Abstract:||We have constructed a new (UV) radiometry facility at the Synchrotron Ultraviolet Radiation Facility [SURF II] at the National Institute of Standards and Technology (NIST). The facility combines a high-throughput normal-incidence monochromator with an absolute cryogenic radiometer [ARC] optimized for UV measurements to provide absolute detector-based radiometric calibrations in the spectral range from 125 nm to approximately 320 nm. The system can be configured for spectroradiometric calibration of photodetectors with completely automated mapping of detector spatial and angular responsivity. The facility can easily be adapted for other spectroradiometric measurements including transmittance and reflectance and the spectral range can be extended to about 50 nm.|
