More info

We are known for offering one of the largest and most versatile ranges of UV light meters respectively measurement instruments on the market. We build on a special modular product concept and complement it with application-specific calibrations by means of spectral mismatch correction in order to provide our customers with the lowest possible measurement uncertainty in the application. See also our UV Brochure.

We also offer innovations such as the MDC4 series with centroid wavelength determination in a broadband measuring head using a multidiode concept. This makes it possible to obtain a wavelength statement in addition to the intensity and thus to obtain a dynamic automatic calibration factor selection with low measurement uncertainty as a Plug&Play UV Light Intensity Meter for LEDs.

For spectral measurements, which are more and more in demand, we also offer absolute High-end spectroradiometers incorporating innovative stray light suppression technologies enabling unsurpassed performance for UV measurements.
