Abstract: We present first preliminary results from AKARI/FIS pointed observations of post-AGB stars and planetary nebulae (PNe). A first analysis of the radial (azimuthally averaged) profile of the observed sources shows no evidence for excess emission due to the presence of circumstellar dust. No (detached) circumstellar faint dust-shells are seen in the image maps. Also, we present here first results of aperture flux photometry at wavelengths of 65, 90, 140 and 160 μm. Results are compared with IRAS flux densities as well as the β release of the FIS Bright Source Catalog. Finally, spectral energy distributions are given, by way of an example, for two individual targets in our sample.
