Compared to the standard IRSL the IRPL signal from K-feldspar is considered as probably being not, but certainly much less affected by fading (Prasad et. al., 2017). It also exhibits a larger dose range, thus allowing the dating of old samples. The required pulsed stimulation and detection of both emissions (880 and 955 nm) is implemented into lexsyg TL/OSL reader, which allows very precise measurements due to the non-destructive nature of the measurement. However, not all samples appear to show a 955 nm emssion and detection at 880 nm might be sufficient.
