Abstract (from CDS):

Mid-infrared images obtained with the TIRCAM camera are presented for a sample of 16 sources including both O-rich and C-rich AGB and post-AGB stars. Photometry and colors are derived using 10% bandwith filters at 8.8, 9.8, 11.7 and 12.5µm. These are compared with photometric data and Low Resolution Spectra (LRS) from IRAS. The observations form the basis for developing photometric criteria suitable to discriminate between O-rich and C-rich sources and to derive mass loss rates. The evolutionary status of the observed stars and the consequences for the mass loss history on the AGB are discussed. Finally, for the C-rich star CW Leo we show evidence for a geometrical extension of the envelope at 12.5µm.
