The UVpad is the world‘s thinnest spectral measuring and autonomous UV radiometer. It combines scientific measurement technology with a compact and user-friendly instrument. With its innovative measuring principle, it doesn't use optical filters.

UV light is spectrally detected and analyzed in the UVpad. Thus, measurements are traceable to national standards. Since it works without a filter, it is particularly suitable for the measurement and comparison of different lamps.
All measurement data are displayed on the device immediately; 50 measurements are stored in the UVpad and can be read via USB. The supplied PC software evaluates the irradiance intensity profiles measured separately for UVA, UVB, UVC, and VIS. Spectrum and measurement data can be exported and saved.

Optionally, UV systems can be optimized due to saved operating functions such as, for example, the absorption spectra of photo initiators. Thus, the operation costs can be reduced and the product quality can be ensured.

 

Notes for spectroradiometer and broadband radiometer

Broadband and spectral radiometers are used in the UV measurement technology to monitor lamp performance. However, broadband radiometers are only calibrated to one lamp type and differ in their sensitivity to each other. This makes comparisons between the measurements of different manufacturers and comparisons between systems with different lamps (e.g., Hg, Ga, Fe) or UV LEDs impossible. In contrast, by means of spectral radiometers, all UV lamps can be measured.

For example, as doped radiation sources age, the spectrum changes. UV systems and aging of the radiation sources can be conveniently monitored and documented with the UVpad.
