We present a measurement of the quasar luminosity function in the range 0.682.15. Using pure luminosity evolution models, we fitted our LF measurements combined with the data from Croom et al. (2009), and predicted quasar number counts as a function of redshift and observed magnitude. These predictions are useful inputs for future cosmology surveys such as those relying on the observation of quasars to measure baryon acoustic oscillations.
