Abstract

The feasibility of using optical fibers as solar radiation collectors in radiometric measurement devices and instruments is discussed, taking into account the various characteristics of the fibers that affect the measurements, with a special focus on numerical aperture. The discussion is supported by various results using the fiber to measure direct normal irradiance.
