Abstract: The ALPS II experiment, Any Light Particle Search II at DESY in Hamburg, will look for light ($m< 10^{-4}$eV) new fundamental bosons (e.g., axion-like particles, hidden photons and other WISPs) in the next years by the mean of a light-shining-through-the-wall setup. The ALPS II photosensor is a Transition-Edge Sensor (TES) optimized for $\lambda=1064$ nm photons. The detector is routinely operated at 80 mK, allowing single infrared photon detections as well as non-dispersive spectroscopy with very low background rates. The demonstrated quantum efficiency for such TES is up to 95% at $\lambda=1064$,nm as shown in [1]. For 1064 nm photons, the measured background rate is $< 10^{-2}$sec$^{-1}$ and the intrinsic dark count rate in a dark environment was found to be of $1.0 \cdot10^{-4}$sec$^{-1}$ [2]. Latest characterization results are discussed.
