— 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 are 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 cutoff filters are used. The most severe discrepancy appears with the UV‐B meter reading, although the UV‐A reading can also be problematic. Meters should be calibrated against the specific sources they will be used to measure.
