The Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) is a set of four reflecting telescopes designed to acquire high-resolution images of the solar atmosphere in a variety of extreme ultraviolet, ultraviolet and visible-light wavelength bands (see Lemen et al.). AIA takes images in ten wavelength channels, whose bandpasses are determined by the collecting area dedicated to each channel and the efficiency of the mirror coatings, filters, and detector. We describe the measurements of each of these components, and present the resulting effective area as functions of wavelength. The measured effective area functions will be cross-calibrated on orbit by comparing full-disk integrated fluxes from each of the AIA channels with the calibrated irradiance measurements from the EUV Variability Experiment (EVE) on SDO. The AIA effective areas are used to calculate temperature response functions and expected count rates in each channel for observations of various solar features.
