Measurement in transmission or reflection mode (also ATR) of polymer materials allows to track material aging.

Enable measurement in transmission or reflection mode (also ATR) of polymer materials:

  • material detection
  • ageing tracking

UV-VIS-NIR-Spectroscopy

The measurement in the UV-VIS-NIR spectroscope is used to follow the formation of chromophores, the degradation of UV absorbers and the transparency of polymer films.

Measurement in transmission or reflection mode in the spectral range between 200 and 2000 nm for the purpose of tracking:

  • chromophore formation
  • degradation of UV absorbers
  • transparency of the polymer films

Spectrophotometry
