Lamp calibrated UV irradiance is the irradiance in Watts per (square meter per nanometer) measured by the UV MFRSR that has been calibrated using a NIST traceable lamp in laboratory setting. Our lamp-calibrated irradiances are from each nominal wavelength of the UV Shadowband (300, 305, 311, 317, 325, 332, 368 nm).

Graphs of the data are available for a time selection of a month or less. The graphs will be displayed along with a tabular view of the data used to create the graph. We also provide a feature to export the data to a file on your local computer in a comma delimited(CSV) format.

For any time duration greater than a month, use the end date option below. This will generate a data file that you can download to your local computer. Keep in mind a year's worth of data is about 25 megabytes, and will take almost 2 minutes to generate.
