Reference systems for UV-LED production

UV_LEDUV-LED lab measuring stations are for testing new products or, e.g. building reference systems for UV-LED production. In order to cater for new measurement scenarios, the individual system components of the high-end portfolio from Instrument Systems are subject to ongoing technological improvement.

Key Features:

  • High sensitivity in the UV from 200 nm
  • Calibration traceable to PTB
  • Very low stray light level
  • Optional: stray light correction matrix for best-possible measurement accuracy


Reliable and accurate measurement of the radiant flux of UV-LEDs calls for extremely sensitive optical measurement systems for precise radiometric characterization. This is particularly applicable to the spectral range of UVB and UVC-LEDs that typically have a comparatively low optical power.

Individual configuration

The multitude of product versions and optional accessories make this highly flexible system solution from Instrument Systems ideal for extensive measurement of UV-LEDs during the development process or in quality control.

Our system experts will be pleased to provide competent advice on your particular application. Together we will find the right solution – just ask us!
