title: Discrepancies in the measurement of spectral sources.
abstract: Comparison of spectroradiometric and meter measurements of a series of ultraviolet radiation sources indicates that a wide divergence between readings can occur. We found that with a xenon arc filtered as a solar simulator producing UV-A (320-400 nm) and UV-B (290-320 nm) radiation, the meter can either over- or underestimate the emission of the source when different cut-off filters are used. The most severe the UV-B meter reading, although the UV-A reading can also reading can reading can also be problematic. Meters should be calibrated used to measure.
