Illumination equipment and measurement devices

MRC offers a modular illumination chamber for reproducible photoactivation of samples as well as flexible LED-based optical arrangements for illumination of anti-bacterial or self-cleaning products. The illumination is based on different light sources and intelligent electronic controls. The system can be customized for specific applications with special design requirements and geometries.

We also offer measurement tools for the simultaneous determination of the photocatalytic activity.

The photos above show a UV illumination chamber in the standard configuration (left) and the transmission measurement through a Petri dish filled with methylene blue (right). The measurement can be integrated into the chamber.

Further product information

Our UV LED illumination unit can be used for a homogeneous illumination of samples. The LED illumination unit including a lens assures a homogeneous light distribution with a very high parallelism of the light. The high light intensity at 365nm enables the activation of photocatalytic materials and samples.

Measurement of photocatalytic activity

The detection system comprises a stabilized light source and a sensitive, calibrated photodiode. It enables the user-friendly measurement of light transmitted through a dyed fluid or other transparent materials. As an example the degradation of methylene blue during photocatalysis can be observed in accordance with the German standard DIN 52980 "Photocatalytic activity of surfaces - Determination of photocatalytic activity by degradation of methylene blue". A laser diode with a wavelength of 664nm can be used that matches the absorption peak of the dye.


  • continuous measurement by a flow through cuvette or a measurement frame
  • integrated peristaltic pump for the sample solution
  • software for automatic data acquisition and analysis available
