UD-T3040T2(Receiver for UVR-T2)

UD-T3040T2(Receiver for UVR-T2)


Due to the distribution response characteristics in a wide range of flat ultraviolet wavelength regions, it is possible to measure the light intensity within the sensitivity range of 290-430nm without depending on the emission wavelength distribution of UV-LED, so the variation in emission wavelength of UV-LED Reduced measurement is possible.
The heat resistance has been increased from 40 ℃ to 60 ℃, which is currently on the market, making it the most suitable specification for lamp intensity management of conveyor type irradiation equipment used at high temperatures. Please use in combination with UVR-T2.

  • ・Measurements with reduced variation in UV-LED emission distribution are possible.
  • ・Spectral response characteristics in a wide range of flat ultraviolet wavelengths of 290-430nm.
  • ・Supports measurement of radiation limit(mW / ㎠), peak irradiance (mW / ㎠), and integrated value (mJ / ㎠).
