This paper summarises the first work on the characterization of a back-thinned Vanilla - a 512x512 (25$\mu$m squared) active pixel sensor. Characterization of the detectors was carried out through the analysis of Photon Transfer Curves to yield a measurement of full well capacity, noise levels, gain constants and linearity. Spectral characterization of the sensors was also performed in the Visible and UV regions. A full comparison against non back-thinned front illuminated Vanilla sensors is included. Such measurements suggest that the Vanilla APS will be suitable for a wide range of applications including particle physics and biomedical imaging.
