Measures peak irradiance and Total energy of UV-A light Pulse.
The PMA2115 UVA flash detector provides for accurate peak irradiance measurements in the UVA region. See figure 1 for spectral response. This detector is ideal for measuring flash lamps commonly used for UV curing.

The peak intensity of a flash is much higher than a continuous source. The PMA2115 UVA flash detector captures the peak intensity and displays it on the PMA2100 for a period of 5 seconds. In addition to the peak intensity, the PMA2115 also integrates and holds the dose of a single pulse.

The peak intensity of the radiation is measured in mW/cm2 or W/cm2. When used with the model PMA2100 meter UVA measurements can be made with a full scale of 600 W/cm2 at a 1 mW/cm2 resolution. The dose has a full scale of 600 J/cm2 with a resolution of 1 mJ/cm2. The PMA2115 can measure pulse with a width of 100µs to 1s.

The photodetector has an active area of 0.474 inches

The Teflon hemisphere results in the UVA detector having an exceptionally good cosine response. This response allows accurate measurement of both point and extended light sources.
