Lamp Measured Irradiance

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).

The Visible (Lamp Calibrated) data are Visible MFRSR data calibrated using coefficients derived from lamp calibrations. These calibrations are dated as they were supplied by the manufacturer at the time of instrument acquisition.

Graphs of the data are available for a time selection of two months or less. Also provided, is a feature to export the data to a file on your local computer in several different formats(excel, csv, xml).Keep in mind a year's worth of data is about 25 megabytes, and will take almost 2 minutes to generate.
