High resolution infrared imaging observations of the young Planetary NebulaeNGC 7027 and BD +303639, taken with the newly installed TIFR Infrared Camera-II(TIRCAM2) on 3.6m Devasthal Optical Telescope (DOT), ARIES, Nainital, are beingreported. The images are acquired in J, H, K, polycyclic aromatic hydrocarbon(PAH) and narrow-band L (nbL) filters. The observations show emission from warmdust and PAHs in the circumstellar shells. The imaging of the two objects areamong the first observations in PAH and nbL bands using TIRCAM2 on DOT. The NGC7027 images in all bands show similar elliptical morphology with ~6".7 and~4".5 semi-major and semi-minor axes. Considering size up to 10% of peak valuethe nebula extends upto 8" from the central star revealing a multipolarevolution. The relatively cooler BD +303639 shows a rectangular-ring shapednebula. In J and H bands it shows an angular diameter of ~8", while a smaller~6".9 size is observed in K, PAH and nbL bands. The 3.28 micron emissionindicates presence of PAHs at about 6000 and 5000 AU from the central stars inNGC 7027 and BD +303639 respectively. Analysis suggests domination of neutralPAHs in BD+303639, while in NGC 7027 there is higher ionization and moreprocessed PAH population.
