The Only Certified Measuring Device
for the Optical Transmittance of Plastic.

THE Reference for Transmittance Measurement

Measuring device with reference standard, traceable calibrated in cooperation with Fraunhofer ISC

The optical transmittance of the plastic is decisive for the quality of the joint during laser plastic welding. Checking the material properties before the joining process pays off as part of holistic quality assurance. For best joining results. For the best of your products.

Stay ahead of the state-of-the-art

A must for every quality engineer

  • Quality assurance of the preceding compounding or injection moulding process    
  • Validation of weldability, process sampling    
  • 100 % material qualification before the welding process     
  • Inspection of incoming good
