Absolute Calibration of a Large-diameter Light Source

arXiv:1305.1329 · doi:10.1088/1748-0221/8/05/P05014

Abstract

A method of absolute calibration for large aperture optical systems is presented, using the example of the Pierre Auger Observatory fluorescence detectors. A 2.5 m diameter light source illuminated by an ultra--violet light emitting diode is calibrated with an overall uncertainty of 2.1 % at a wavelength of 365 nm.
