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 UV-B and UVC-LEDs that typically have a comparatively low optical power. Numerous applications, especially disinfection of water and surfaces during the pandemic are based on precisely specified UV radiation. For UV-C emitters, between 280 nm down to 200 nm, used for these applications, the measurement is generally challenging. Instrument Systems GmbH is pioneering this area of spectral measurements.

Instrument Systems provides a measurement system consisting of an integrating sphere with PTFE-coating and a highly precise spectroradiometer for fast 24/7 quality control.

Our system experts will be pleased to provide competent advice on your particular application. Together we will find the right solution don't hesitate to contact us!

UV LED Measurement Application Note

Learn about the possibilities and advantages of the application of the stray light matrix in the Application Note entitled "Stray Light Correction for Array Spectroradiometers". Discussion of precise measurements of spectral lines and the impact of stray light correction on broadband sources for spectral calibration in addition to the stray light correction as it pertains in the ultraviolet range.

Application Note

Measuring Blue Light Hazard

The blue light hazard (BLH) measuring station from Instrument Systems evaluates and classifies LED lamps and luminaires according to blue light hazard as described in Standards IEC 62471 and IEC/TR 62778.

These individual system components in its high-end portfolio are consistently ongoing technological upgrades to ensure that they satisfy current requirements. Precise BLH measurements on the basis of the established CAS 140D spectroradiometer guarantee the greatest possible safety in the classification of tested lamps and luminaires in die BLH risk classes.
