Measurement of light
UV contract measurements and photometry
The Opsytec UV laboratory performs contract measurements and calibrations for optical radiation – spectral irradiance, irradiance and illuminance, luminance, transmission and reflection. Its equipment includes UV-VIS double monochromators, spectroradiometers, luminance meters and calibration light sources. All measurements are traceable to national and international standards.
Factory calibrations – for example of DVGW sensors in accordance with DIN 19294 – are carried out in our calibration laboratory.
In our UV laboratory measurements and factory calibrations are available:
- Calibration, traceable to national standards with manufacturers certficates of calibration
- Calibrations of dosimeters and devices of type UV integrator to irradiation dose
- Calibration of DVGW sensors for drinking water disinfection in accordance with DIN 19294-1:2020-08 and DIN 19294-3:2020-08 (low pressure) as well as DIN 19294-2:2026-04 and DIN 19294-4:2026-04 (medium pressure)
- Low-pressure mercury lamps (253.7 nm)
- Medium-pressure mercury lamps (240–290 nm)
- UV LEDs (255, 265, 270, 275, 278 and 280 nm) – for development applications
- Linearity tests of UV measuring devices up to approx. 5 W/cm²
- Photometric measurements
- Spectroscopy (VUV, UV, VIS, IR)
- Absorption, reflection, and transmission measurements
- Measurement of optical density
- Time-resolved measurements
- Luminance measurements
- LED measurements
- Preliminary investigations
In addition, we offer measurements at your facility:
