Spectra of UV lamps and UV LEDs

Our database offers precise and reliable spectra of a wide range of UV LEDs and UV lamps. The spectra are typical for the respective class. Therefore, we do not provide type designations. 

All spectra were measured in our laboratory and can be used freely. The measurements were performed in accordance with CIE 250:2022 „Spectroradiometric Measurement of Optical Radiation Sources". We have also provided some information on various UV light sources. If you have any questions or queries, please do not hesitate to contact us.

The UV-A, UV-B and UV-C components of the emission can be calculated from the spectra. Instructions on how to calculate the irradiance from the spectral irradiance can be found here.
