UV LED technology at the highest level

MR® UV luminaires are based on the long-lasting and energy-efficient LED technology and were developed especially for industrial use. Most of the UV lamps offered are classified in the IP64 enclosure and are therefore dust-proof and splash-proof.

MR® UV lamps are primarily used in non-destructive crack detection (ZfP). Here especially in the penetration test and magnetic particle inspection. In practice, this is also referred to as UV test lamps.

They are also used in the following areas:

  • Research
  • Leakage test
  • Penetration testing
  • Medicine
  • Criminology
  • Building renovation
  • Hygiene beings
  • Security technology
  • Effective testing of extraction systems
  • Mineralogy
  • Geocaching

Advantages of the MR® UV-lamps:

  • No harmful UVB/UVC radiation
  • Durable LED technology
  • Sturdy housing
  • Low maintenance
  • Quality – Made in Germany
  • Homogeneous illumination


DIN EN ISO 3059 – Non-destructive testing – Penetration testing and magnetic particle testing – Viewing conditions

UV lamps for fluorescent crack testing must meet certain criteria. These are defined in the standard DIN EN ISO 3059.

The wavelength must be 365 ± 5 nm, and the full width at half maximum (FWHM) should be 30 nm. In addition, the illumination should be homogenous.
