The late stages of stellar evolution of stars with low or intermediate mass (1 M⊙ to 8 M⊙) are characterized by extensive mass loss, which can be traced in their circumstellar environment. Here we consider the case of IRAS 16342-3814, a bipolar proto planetary nebula which shows very high velocity (~ 50 km s-1) OH maser emission (Sahai et al. 1999). We present the complete Infrared Space Observatory (ISO) spectrum and an infrared TIMMI2 Q-band image of this source. Based on these data we discuss the composition and geometry of the circumstellar dust in IRAS 16342-3814.
