Plastic infrared transmission
Webb8 sep. 2024 · Spectral Identification of Plastic Parts The main spectral method for industrial plastic identification is near infrared spectroscopy. Rugged detector systems based on indium gallium arsenide (InGaAs) material can be applied which are sensitive and fast enough for sorting applications. Webb1 sep. 2024 · Recently, the possibility of detecting rough transparent small plastics from the measured near-infra red (NIR) transmission spectra and the dispersion of the refractive index of the plastics have been demonstrated.

Webb30 sep. 2016 · I suggest polyethylene would absorb the least because of the lack of strongly absorbing functional groups. Styrenics absorb across a broader range of IR than other plastics. Anything with carbonyl functionality will strongly absorb between 1600 and 1750 cm -1. Polyesters, polycarbonates and acrylics absorb around 1745 cm -1.
WebbUnlike visible and infrared light, THz radiation can penetrate certain organic materials such as skin, plastics, textile and paper. Due to low photon energy, it doesn’t cause damage associated with ionizing radiation (e. g. X-rays).
