UV LED measurement system

The efficiency of UV LED depends on the junction temperature. The thermal change of the PN junction will affect the optical power output and life expectancy of UV LED. Using TEMPOint’s UV LED measurement system, users can quickly and accurately test UV LED performance (single point test , Variable current, variable temperature test).

Application areas:

  • Germicidal ultraviolet (GUV)
  • UVC disinfection and purification
  • UV curing
  • Medical phototherapy
  • Analytical Instruments
  • Garden lighting


  • Absolute radiant flux (W) above 200nm can be measured
  • Data can be traced to JCSS or NIST
  • Optional power supply (programmable)
  • Temperature controller (programmable) is optional
  • The instrument can do absolute value calibration in Taiwan
