Transmission sensors are used for the quality assurance of weld seams. The LPKF TMG 3 transmission measuring device determines the amount of laser radiation transmitted through a sample of plastic pursuant to DVS Regulation 2243 with the wavelength of a common welding laser.
The beam intensity measured without a sample in the beam path is the reference level. A laser beam is then sent through the sample and its intensity determined where the beam exits the sample. Thanks to an additional calibration with certified measuring standards, the measurement meets the requirements of DIN 9001.
An optional component specific holder ensures reliable and reproducible test results. Detects transmission fluctuations between components with an accuracy of ≤ 1 per cent. Insensitive to light interference.
